Answer:

Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
In this problem we have that
The line pass through the points
<em>Find the value of the constant of proportionality k</em>
For x=2/5, y=1/2
substitute


Answer:
Step-by-step explanation:
-3x + 9y = -24
3x + 3y = 24
12y = 0
y = 0
-3x + 9(0) = -24
-3x = -24
x = 8
(8,0)
