Question

Find the slope, vertical intercept and horizontal intercept of (2,9) and (4,3)​

Answer 1

M = - 3

Explanation:

Find the Slope:

Slope is equal to the change in y over the change in x

, or rise over run.

m =
`(change in Y)/(change in X)`

The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).

m =
`(y_(2)-y_(1) )/(x_(2)-x_(1))`

Substitute in the values of x and y into the equation to find the slope.

m =
`(3-(9))/(4-(2))`

Simplify.

m =
`(-6)/(2)`

m = -3
