Question

Find the slope of the line containing the pair of points. (2, -9) and (12,6)

Answer 1

Answer:

slope = $\frac{3}{2}$

Step-by-step explanation:

calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (2, - 9 ) and (x₂, y₂ ) = (12, 6 )

m = $\frac{6-(-9)}{12-2}$ = $\frac{6+9}{10}$ = $\frac{15}{10}$ = $\frac{3}{2}$
