Question

Which of the following choices is a good estimate for the slope of the Line of Best Fit in the scatter plot?

Answer 1

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

$m=\frac{y2-y1}{x2-x1}$

From the graph take the points

(0,0) and (80,125)

substitute

$m=\frac{125-0}{80-0}$

$m=\frac{125}{80}$

simplify

$m=\frac{25}{16}$

Multiply by 3.75 both numerator and denominator

$m=\frac{25*3.75}{16*3.75}$

$m=\frac{93.75}{60}$

$m=\frac{94}{60}$

therefore

A good estimate for the slope is 95/60
