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 this problem
For x=32, y=-4
Find the value of the constant of proportionality k
substitute
simplify
so
The linear equation is
Find x when the value of y=0
Remember that
In a proportional relationship <u><em>the line passes through the origin</em></u>
so
If y=0
then
the value of x must be equal to zero
therefore
