Answer: C
Step-by-step explanation:
y = mx + b
To get ‘b’ look at the y intercepts.
Both y intercepts are 7 and - 1
For this problem it’s all you need, since the only equations with b being - 1 and 7 is C.
Answer:
The x -coordinate(s) of the point(s) of intersection of these two polynomials are 
The sum of these x -coordinates is 
Step-by-step explanation:
The intersections of the two polynomials, p(x) and q(x), are the roots of the equation p(x) = q(x).
Thus,
and we solve for x

Using Zero Factor Theorem: = 0 if and only if = 0 or = 0


The solutions are:

The sum of these x -coordinates is

We can check our work with the graph of the two polynomials.
Answer:
can you show the other answers to see if I have the answer sorry.
You add each step from +5 to +10 to get 55
