Step-by-step explanation:
<span>m</span> = -4
<span>m</span>-4=2m
-4+m=2m (reorder)
-4 + 1m + -2m = 2m + -2m (added -2m to both sides)
-4+ -1m =0 (added like terms)
-4 +4+ -1m = 0+4 (added 4 to each side)
-1m = 4
m=-4 (divided by -1)
It is 90
When something is perpendicular it means it is at a 90 degree angle
An infinite number of solutions means a coincident line...it is the same line
3y = 2x - 9...divide by 3
y = 2/3x - 3...hmm...same line as answer choice b....they are coincident lines and have infinite solutions
