, we can plug in and solve for b. When we plug into the formula we get:
= 
First multiply by 2 on both sides to get rid of the 1/2 on the left. After doing this we get:

Then we can multiply by 5 on both sides to get rid of the 1/5 on the left. After doing this we get out answer:

The x intercept is 9
The y intercept is -3
Answer:
