Question

find the slope of the line that passes through each pair of pointa(-3, -1), (-1, 5)

Answer 1

To find the slope we use the formula

$m=\frac{y2-y1}{x2-x1}$

where (x2,y2) is a right point from (x1,y1)

on this case (-1,5) is (x2,y2) and (-3,-1) is (x1,y1)

then replacing

$\begin{gathered} m=\frac{(5)-(-1)}{(-1)-(-3)} \\ \\ m=\frac{6}{2}=3 \end{gathered}$

The slope of the line is 3
