They way to find the y-intercept from two points is to first find the slope, which can be derived from the formula
.
Then, you can plug in one of the two points
or
into the formula y=mx+b to solve for b, which is your y-intercept.
Answer:
A, C, D, F, G. I believe so?
How does this have anything to do with factoring?
Perimeter of the rectangle would just be 2(3t-2)+2(5t+7)
Simplify that to get 6t-4+10t+14, then 16t+10
