both halves of a diagonal must be equal.

so,

8b - 30 = 6b + 6

2b = 36

b = 18

9a - 13 = 5a + 5

4a = 18

a = 18/4 = 4.5

What is the y-intercept for the below inequality?

san4es73 [151]

Answer:

The correct answer is C

Step-by-step explanation:

In order to find the y-intercept, you need to first solve the inequality for y.

5x - 3y ≤ 15

-3y ≤ -5x + 15

y ≥ 5/3x - 5

Now we look at the constant at the end. Since that constant is -5, we know C to be the answer.
