Question

Write the equation 6x − 3y = −12 in the form y = mx + b.

Answer 1

Solve for the variable y (move the x to the right of equal with changed sign)

M is the coefficient before the x and b is the known number

-3y = -12 - 6x

Since the y can't be negative, multiply every term for -1, therefore change their sign

3y = 6x + 12

To find y, divide both terms for 3

$\frac{3}{3}y = \frac{6x+12}{3}$

y = 2x+4

Therefore your answer is y = 2x+4
