Answer:
A good estimate for the slope is 95/60
Step-by-step explanation:
The formula to calculate the slope between two points is equal to
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
From the graph take the points
(0,0) and (80,125)
substitute
[tex]m=\frac{125-0}{80-0}[/tex]
[tex]m=\frac{125}{80}[/tex]
simplify
[tex]m=\frac{25}{16}[/tex]
Multiply by 3.75 both numerator and denominator
[tex]m=\frac{25*3.75}{16*3.75}[/tex]
[tex]m=\frac{93.75}{60}[/tex]
[tex]m=\frac{94}{60}[/tex]
therefore
A good estimate for the slope is 95/60
