Answer 1

x = -7/5

Explanation:

Zeros of the equation are the x-values where y = 0

-5x - 7 = 0

-5x = 7

x = -7/5

Answer 2

The zero of this function is
`-(7)/(5)`.

Explanation:

Zeros are x-intercepts or when y is equal to 0.

Let's substitute 0 in for y and find the x-intercept.

0 = -5x - 7 (Add 7 to both sides)

7 = -5x (Divide both sides by -5)

x =
`-(7)/(5)`

The zero of this function is
`-(7)/(5)`.
