Answer:
y = -15/8x - 35/8
Step-by-step explanation:
Find the slope = [tex]\frac{change in y}{change in x}[/tex]
= [tex]\frac{80 - 5}{-45 - (-5}[/tex])
= [tex]\frac{75}{-40}[/tex]
= [tex]\frac{-15}{8}[/tex]
Find the y-intercept Use one point (-5, 5) and the slope [tex]\frac{-15}{8}[/tex]
y = mx + b
5 = -15/8 (-5) + b
5 = 75/8 + b
5 - 75/8 = b
-35/8 = b
Write the equation
y = -15/8x - 35/8
