Question

1. What is the y-intercept?

4x+5y = -15
a. (3, 0)
b. (0,-3)
c. (x, 0)
d. (y, 0)

Answer 1

The y-intercept is answer b. (0, -3)

Explanation:

To find the y-intercept, fill in x with 0.

4x + 5y = -15

4(0) + 5y = -15

0 + 5y = -15

5y = -15

y = -3

So, the y-intercept would be (0, -3).
