How do you find the slope given (3, 1), (9, 4)?

1 Answer

Dec 28, 2015

The formula to find the slope of a line is $\frac{y 2 - y 1}{x 2 - x 1}$ $(y2 - y1)/(x2 - x1)$

Explanation:

Assuming m represents slope.

m = $\frac{y 2 - y 1}{x 2 - x 1}$ $(y2 - y1) / (x2 - x1)$

m = $\frac{4 - 1}{9 - 3}$ $(4 - 1) / (9 - 3)$

m = $\frac{3}{6}$ $3/6$

m= $\frac{1}{2}$ $1/2$

Hopefully you understand now.
