The slope is usually derived from the equation y = mx + b where m is the slope and b is the y-intercept.
Slope:
m = (y2 - y1)/(x2 - x1)
As for finding intercepts, for finding the y intercept, look for the b in the equation or make x = 0, for x-intercepts, make y = 0.

What is the slope of the line that passes through the given points?
The slope of a line that passes through two points is (difference in y) / (difference in x).
How can you find the slope of a line by only knowing the coordinates?
If you have the coordinates of two points, say P = (a,b) and Q = (c,d), then slope = (b-d)/(a-c) that is, the difference in the y coordinate of the two points divided by the difference in the x coordinate of the points taken in the same order.
What if there is no slope stated in the math question?
Answer: When there is no slope stated in the function of x, when y=mx+b It simply means y=0x+b Since "b" is the y intercept, your line would be a horizontal line parallel to the X-axis passing through point (0,b) Answer: In other cases, you may need to calculate the slope first, from some other information provided. For example, if you are asked to find the equation that passes through two specified points, you can first find the slope between those two points. Then you can use this slope, and one of the points, with the slope-intercept form of the equation.
What is the equation of a line that passes through the points 2 5 and 4 3?
Points: (2, 5) and (4, 3) Slope: -1 Equation: y = -x+7 in slope-intercept form --- If you want to write the slope-intercept form of the equation of the line passing through the given points, then use the two points to find the slope of the line. After that, use the slope and one of the points to find the y-intercept. For instance, m = (5 - 3)/(2 - 4) = 2/-2 = -1(the slope) y = mx + b (replace m with -1, and (x, y) with (4, 3)) 3 = -1(4) + b 3 = -4 + b (add 4 to both sides) 7 = b Thus, y = -x + 7 is the equation of the line passing through (2, 5) and (4, 3).
How calculate the slope of a line?
Using any two points, calculate the differences in the Y and the X coordinates. Then take the difference between the Y and divide it by the difference in the X. Example: Points (1,3) and (4,9) are on a line. Determine the slope of the line. X coordinates: 1 and 4. 4-1 = 3 Y coordinates: 3 and 9 9-3 = 6 Slope = Y/X = 6/3 = 2 The slope is 2
How do you find the slope when given two points?
Points: (x, y) and (x2, y2) Slope = y2-y divided by x2-x
How do you find slope using x and y intercepts?
Your x and y intercepts give you two points on the line of the graph. Use these two points in the slope equation m = (y2-y1)/(x2-x1), and that gives you the slope.
Find the slope of the line passing through the points 2 5 and 0 4?
The slope of the line passing through any two points with coordinates x,y and x',y' is (y' - y)/(x' - x). In this instance, the slope is (5 - 4)/(0 - 2) = -1/2 .
How do you ind the slope of a line?
To find the slope of a line, you take two points on the line, then use their X and Y coordinates in the following formula: slope = ( Y2 -Y1 ) / ( X2 - X1) By simplifying the answer, you will get your slope.
What is the slope of the line that passes through the given points?
The slope of a line that passes through two points is (difference in y) / (difference in x).
Find the slope of the line through the points -13 and 17?
There is not enough information to answer this question. As currently written, a geometric point with only one variable is operating only on the x-axis (one dimensional). Asking the slope between two points that only exist on the x-axis is automatically zero. Slope is normally calculated using points on a two-dimesional grid with each point being represented by (x,y). To calculate the slope in this case you take the change in y divided by the change in x. Example: Find the slope of the line through the points (-13,4) and (17,14). Slope = Change in Y/Change in X = (-13-17)/(4-14) = -30/-10 = 3
How do you find the slope of a line from its graph what is the formula for m?
The slope of a line is the rise divided by the run. In other terms, if, X = the horizontal distance between two points on a line and Y = the vertical distance between the same points, then m = Y/X
How do you find The equation of a line given two points needed?
First, you calculate the slope between the two points (difference of y / difference of x). Then you can use the equation, using one of the points (x1, y1): y - y1 = m(x - x1) Just replace x1 and y1 with the coordinates of the point, and m with with the slope.
How can you find the slope of a line by only knowing the coordinates?
If you have the coordinates of two points, say P = (a,b) and Q = (c,d), then slope = (b-d)/(a-c) that is, the difference in the y coordinate of the two points divided by the difference in the x coordinate of the points taken in the same order.
How do you find the slope of a line passing through a given pair of points?
To find the slope of a line passing through a given pair of points is found by using the point slope formula. Y(2)-Y(1) over x(2) -x(1).
How do you find the slope of a line when they give you the x and y coordinates?
-- If they give you one set of 'x' and 'y' coordinates, then you have the location ofone point on the line. One point doesn't have a slope.-- If they give you two sets of 'x' and 'y' coordinates, then you have the locations oftwo points on the line. The slope of the straight line between two points is(the difference between the 'y' values) divided by (the difference between the 'x' values)
What is the slope of -4 4 and 0 2?
If those are the x-y coordinates of two points, then they're two points. Two points don't have a slope. In fact, points don't have anything. If we want to play around with two points for a while, one thing we could do with them would be to draw a line segment between them. With these particular two points, the line segment would be about 4.472 long, its slope would be -2, and it would be a piece of the line that intersects the y-axis at y=2 and the x-axis at x=4 .
