Answer:

Step-by-step explanation:
Proportional functions can be represented by
, where
is a constant of proportionality and
represents any point the line passes through.
In the graph, we can see the line passes through (20, 40). Therefore, we can plug in these coordinates to find the constant of proportionality:

Answer:

Step-by-step explanation:
Switch Sides

Subtract 2 From Both Sides

Simplify

Multiply Both Sides By -6

Simplify

slope = change in y/ change in x
select two points on the line
(-4,4)
(0,1)
= (4-1)/(-4-0)
= -3/4
