Question

12x+16y=336
Please help me find y intercept the answer should be 28 but guide me on the steps

Answer 1

12x + 16y = 336.
(move x to the right side, to have y by itself. so -12x on both sides)

16y = -12x + 336
(now divide each number by 16 to get Y on its own)

y = -12/16x + 336/16

y = -3/4x + 21

slope= -3/4
y-intercept= 21
