Answer:
Its B - 36 units, you mulitply the last two numbers then add the first,
Step-by-step explanation:
Change -3y + 12 = -8x to the form y = mx + b
Subtract 12 on both sides
-3y = -8x - 12
Divide by -3 on both sides
y = 8/3 + 4
Change original equation to Ax + By = C
-3y + 12 = -8x
Switch -8x and 12
-3y + 8x = -12
(ps, I haven’t done this kind of math in a long time )
Multiply it again so it equals that 310 number
