Answer:
-1/4
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-8-(-5))/(0-(-12))
m=(-8+5)/(0+12)
m=-3/12
simplify
m=-1/4

Answer:
-no solution-
Step-by-step explanation:
When solving problems for systems of equation. You first want to make one of the equations equal to one variable on a side of the equation. In this case, we already have an equation that equals a variable on one side: y = 4x + 20.
you plug in that variable to the other equation
8x - 2(4x + 20) = -20
and then you just solve the equation from there.
8x - 8x + 20 = -20
but by just looking at this, there will be no solution because 8x-8x makes the variable x disappear and 20 does not equal -20.
