Rewrite the equation 4x + 4y = 20 in slope-intercept form.

A. 4x + 4y – 20 = 0
B. x + y = 5
C. y = –x + 5
D. 4y = –4x + 20

Respuesta :

alaixa
4x + 4y = 20

4x + 4x - 4x = 20 - 4x

4y = 20 - 4x

4y / 4 = (20 / 4) + (- 4x / 4)

y = 5 - x

y = - x + 5 (the correct answer is c)

The correct answer is C. Y = -x + 5
