Answer:

im pretty sure #9 is just y=7x... it should be parallel with y=7x-3 since it has y intercept of 0 rather than -3.

Answer:

$y=-\frac{1}{4}x+40$

Step-by-step explanation:

Given

See attachment for graph

Required

Determine the equation of the line of best fit

First, calculate the slope (m)

$m = \frac{y_2 - y_1}{x_2 - x_1}$

From the graph, we can have:

$(x_1,y_1) = (20,35)$

$(x_2,y_2) = (60,25)$

So, the slope is:

$m = \frac{25 -35}{60 - 20}$

$m = \frac{-10}{40}$

$m = -\frac{1}{4}$

The equation is then calculated as:

$y = m(x - x_1) + y_1$

$y = -\frac{1}{4}(x - 20) + 35$

$y = -\frac{1}{4}x + 5 + 35$

$y=-\frac{1}{4}x+40$

<em>Hence, the equation is:</em> $y=-\frac{1}{4}x+40$
