Question

Change each equation below into y = mx + b form. a. y - 4x = -3 b. 3y - 3x = 9 c. 3x + 2y = 12 d. 2(x - 3) + 3y = 0

Answer 1

a. y=4x-3

b. y=x+3

c. y=3/2x+6

d. y=-2/3x+2

Explanation:

a. y-4x=-3

+4x +4x

y=4x+3

b. 3y-3x=9

÷3 ÷3

y-x=3

y=x+3

c. 3x+2y=12

2y=3x+12

y=3/2x+6

d.

2(x-3)+3y=0

2x-6+3y=0

3y=-2x+6

y=-2/3x+2
