Question

For this equation, give two values for x for which the value of y is negative.
(y= -2x-5)

Answer 1

Value 1: -2

Value 2: 10

Explanation:

To make y negative, -2 ≤ x ≤ ∞

In other words, x must be equal to or greater than -2 for the value of y to be negative.

Value 1: -2

y = -2(-2) - 5

y = 4 - 5

y = -1

Value 2: 10

y = -2(10) - 5

y = -20 - 5

y = -25
