Question

Given the formula, y = 3x + 4, enter the value of y in the text box below where the value of x is 2.

Answer 1

-2

Explanation:

Given the function y = 3x + 4, all we have to do is plug in the x-value of -2 to find y.

Given: x = -2

Equation: y = 3x + 4

Substitute x for -2.

y = 3x + 4

y = 3(-2) + 4

y = -6 + 4

y = -2

The y-value is -2.
