How do you find the slope for (1, 3) and (-3, 5)?

1 Answer

Sep 11, 2015

Slope between $(1, 3)$ $(1,3)$ and $(- 3, 5)$ $(-3,5)$ is $- \frac{1}{2}$ $-1/2$

Explanation:

Given 2 points $(x_{1}, y_{1})$ $(x_1,y_1)$ and $(x_{2}, y_{2})$ $(x_2,y_2)$ the slope is defined as
$color(white)("XXX")m=(Delta y)/(Delta x) = (y_2-y_1)/(x_2-x_1)$

For the given points this becomes
$color(white)("XXX")m = (5-3)/((-3)-1) = 2/(-4) = -1/2$
