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
y = 2x+4
Therefore your answer is y = 2x+4
M is the coefficient before the x and b is the known number

Therefore your answer is y = 2x+4
Multiplying by scalars
Answer:
y=3x-5
Step-by-step explanation:
First find the slope, 4+2 over 3-1, giving you the slope of three
then set up your equation, y=3x+?
I played with the y=3x - part on the website desmos graphing calculator, I first inserted the points then found the slope and then played with the equation till it went through both the points.
