Question

What is the gradient of the line 12x=15-3y

Answer 1

-4

Explanation:

12x=15-3y

+3y

12x+3y=15

-12x

3y=-12x+15

/3

y=-4x+15

Gradient= -4 as in the equation y=mx+c

, m=the gradient therefore the gradient is -4

Answer 2

-4

Explanation:

12x=15-3y +3y

12x+3y=15 -12x

3y=-12x+15 /3

y=-4x+15
