Answer:
15. y=-4/3x+7/3
16. y=-1/3x+4
Step-by-step explanation:
answer is c of your question
Yes,a similar formula is used to find all the products
The formula applied in this case is;
(a+b)²= (a+b) (a+b)= a(a+b)+b(a+b) = a²+ab+ab+b²= a²+2ab+b²
In the first one;
In the second one;
⇒This is the same for the third and fourth product.
y=x-1
y=-2x-4
although I cant summon a graph for this one, I can give cords
for first graph (-2,-3),(-1,-2),(0,-1), (1,0),(2,1)
For second graph the slope is down 2 over 1, and begins at (0,-4).
(-2,0)(-1,-2),(0,-4),(1,-6),(2,-8)
