Question

NEED HELP WITH PART B

Answer 1

Answer:

y = -20x + 100

Step-by-step explanation:

As per your requirement For Part B, the solution is

The equation in slope-intercept form to model the relations is below:-

To reach 2 points on the graph the line passes through

lets use p1(0, 100), p2(1, 80)

now we will compute the slope:

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

$m = \frac{(80 - 100)}{(1 - 0)}$

= -20

and now use line equation in form point-slope:

y - y1 = m(x - x1)

y - 100 = -20(x - 0)

y = -20x + 100
