Answer:
slope is 
Step-by-step explanation:
1,-1 -3,2 are two points on the graph
the equation to find slope is 
so 
or you can count how many places it changed in the equation 

As we have to solve for b, it means we have to isolate b
So first of all subtract
from both sides
So we get

Now we need b , but its b^2 , so we can take square root on both sides.
taking square roots on both sides

Hence option B is correct

1. Both are corresponding angles, hence they both are equal, so,

Ans. C) 2
2. They both are in interior corressponding, hence their sum is equal to 180°, so,

Ans. D) 7
3. They both are in interior corressponding, hence their sum is equal to 180°, so,

Ans. A) -10
4. Both are corresponding angles, hence they both are equal, so,

Ans. A) 6
