Answer:

see explanation

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 15, - 14 ) and (x₂, y₂ ) = (- 13, - 10 )

m = [tex]\frac{-10-(-14)}{-13-(-15)}[/tex] = [tex]\frac{-10+14}{-13+15}[/tex] = [tex]\frac{4}{2}[/tex] = 2

A line with a positive slope rises from left to right
