If X=-1
Then to find y you will just subsitute it to your equation.
Y=4x+4
Y=4(-1)+4
Y=-4+4
Y=0
So y=0
The zeros are the points on the x-axis where the graph intersects.
For factorization, you do (x - the zero) for each zero, and multiply them together.
7. A. The zeros are -2 and 4.
The factorization is (x + 2)(x - 4)
7 B. The zeros are 1 and 3.
The factorization is (x - 1)(x - 3)
