First we graph the given points
For the equation to be proportional, the line should pass through the origin (0,0), then this equation is not proportional.
Answer:
<h2><em> -12y² + 72y</em></h2>
Step-by-step explanation:
Use the distributive property: <em>a(b + c) = ab + ac</em>
<em>-12y(y - 6) = (-12y)(y) + (-12y)(-6) = -12y² + 72y</em>
The answer to 4x - 5y = 24 is (6, 0).
