Question

Write the equation of the line in slope-intercept form (y = mx +b): 3y - 12x = 15

Answer 1

ACTUALLY IT'S, y=4x-5

Explanation:

12x-3y=15 - Get y alone

-12x =12x

-3y=-12x+15

-3y=-12x+15 - Divide.

__________

-3 -3

y=12/3x-15/3 - Distribute division. Negative over a negative is positive. Positive over a negative is a negative.

y=4x-5 - Reduce fractions.

Answer 2

y = 4x + 5

Explanation:

3y - 12x = 15

Add 12x to both sides.

3y = 12x + 15

Divide by 3 to isolate y.

y = 4x + 5
