Two coordinates define a point. You need two pairs of two coordinates to define two points and, therefore, a slope.
No.
You need two coordinates, not one, to specify a point. To calculate the slope, simply calculate (difference in y-coordinates) / (difference in x-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.
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
You need two numbers to specify each point.To actually calculate the slope, divide (difference in y-coordinates) by (difference in x-coordinates).If you mean: (-1, 2) and (4, 3) then it is 1/5
No.
The name of the slant on a line graph is called the slope. The slope represents the rate of change between two points on the graph and is calculated by dividing the change in the y-coordinates by the change in the x-coordinates. A positive slope indicates an upward trend, while a negative slope indicates a downward trend.
Two or more coordinates are needed to determine the slope of a line
slope = (delta y) / (delta x). That's shorthand for: slope = (difference in the y-coordinates) / (difference in the x-coordinates). For two given points with coordinates (x1, y1) and (x2, y2), the slope is (y1 - y2) / (x1 - x2).
You need two coordinates, not one, to specify a point. To calculate the slope, simply calculate (difference in y-coordinates) / (difference in x-coordinates).
Coordinates: (-4, 1) and (6, 3)Slope of line: 1/5
The slope of a line passing through two points with given x y coordinates can be found by dividing the (signed) difference between the two y coordinates by the (signed) difference between the two x coordinates, being careful to take the coordinates in the same order for each subtraction. In this instance, the slope is (-4 - 4)/(-1 - 3) = -8/-4 = 2.
To find the slope between two ordered pairs ((x_1, y_1)) and ((x_2, y_2)), you can use the formula: [ \text{slope} (m) = \frac{y_2 - y_1}{x_2 - x_1} ] Subtract the y-coordinates and the x-coordinates of the two points, then divide the difference of the y-coordinates by the difference of the x-coordinates. This gives you the rate of change of y with respect to x.
I believe they are parallel.
Two coordinates are needed to determine the slope of a straight line equation.
In order to calculate the slope, you need two points, each with two coordinates. That makes four numbers in all. There are only two in the question.
The slope for a line between two points is (difference of y-coordinates) divided by (difference of x-coordinates). That is, (y2-y1)/(x2-x1). It doesn't matter in what order you take the points.
