this is how i do it lets say you have m and it is 5. and the two points are (0,9) now all you do is 0 is the x and 9 is the y. so it would be 9y=5(0)x+b so solve for b now. you should get y=5x+9.
you look at the line and see if there are any direct points on the line the slope formula
Points for example: (4, 8) and (2, 4) Slope: (8-4)/(4-2) = 2 The slope formula is m = (y2 - y1) / (x2 - x1) where the 2 points are (x1,y1) and (x2,y2)
No. If you have more than two points for a linear function any two points can be used to find the slope.
find the constant of variation and the slope of the given line from the graph of y=2.5x
Call one point "Point 1" and the other "Point 2". (X1, Y1) are therefore the coordinates of "Point 1", and (X2, Y2) are the coordinates of "Point 2". Plug those values into this formula to get the slope of the line between those two points. m = slope (Y2-Y1)/(X2-X1)=m
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).
Use point-slope formula
Points: )1, 1) and (3, 3) Slope: 1
3 is the slope. The formula is "y = mx + b," and since 3 is in the "m" spot, 3 is our slope. You can also find the slope using two given points and figuring out the difference.

the slope is the 'm' in y=mx+b so even if the points aren't given, if there is an equation, then you can find the slope. for example, if you have an equation like this: y=2x+5 the slope is 2 and the y-intercept is 5.
To find the slope of a line passing through two points, use the formula (y2 - y1) / (x2 - x1). In this case, the two points are (17, 101). Since there is only one given point, it is not possible to find the slope of the line passing through these points.

That depends on the points in order to find the slope whereas no points have been given.
Points: (x, y) and (x2, y2) Slope = y2-y divided by x2-x
To find the slope (steepness, not height) of a line when given two points, do the following: Slope = (y2-y1)/(x2-x1), where (x1, y1) is one point, and (x2,y2) is the second point.
The slope of the line passing through the points (-4, -6) and (-3, -1) can be calculated using the formula: slope = (change in y)/(change in x). Substituting the given coordinates, we find that the slope is 5/1, or simply 5.
