Question

question 8 of 10
what is the slope formula?
a. $\frac{y_{2}-x_{1}}{x_{2}-y_{1}}$
b. $\frac{x_{2}-x_{1}}{y_{2}-y_{1}}$
c. $\frac{x_{2}+x_{1}}{y_{2}+y_{1}}$
d. $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Explanation:

Step1: Recall slope concept

Slope measures steepness of line.

Step2: Know slope formula

For two points $(x_{1},y_{1})$ and $(x_{2},y_{2})$, slope $m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$.

Answer:

D. $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$
