Question

What is the slope, m, of the line through (-7, -2) and (-6, 7)?

Answer 1

Answer:

Slope = 9

Step-by-step explanation:

(-7 , -2) ;  x₁ = -7  and  y₁ = -2

(-6 , 7) ;  x₂ = -6  and y₂ = 7

Slope = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

          $=\frac{7-[-2]}{-6-[-7]}\\\\=\frac{7+2}{-6+7}\\\\=\frac{9}{1}\\\\= 9$
