Question

Rewrite the following equation as a function of x.
56x + 7y + 21 = 0

Answer 1

f (x) = -8x-3

Explanation:

To rewrite the equation as a function of x, first isolate y on one side of the equation.

56x + 7y = -21

56x + 7y = -21

7y = -5x - 21

y = -8x -3

Then, substitute f(x) for y in the equation. This leaves the following as the correct answer.

f (x) = -8x-3
