Answer:
C
Step-by-step explanation:
we should set the equations based on what we know using y=mx+b
in the first set, we have m=5 and the +b as 100. This gives y=5x+100
in the second, we m=20 and the +b of 10. This gives y=20x+10
I belive C would match this. Hope this helps!
y=10x+20
y=5x+100
-16
y = mx
-4 = 1/4x
Divide both sides by 1/4.
-16 = x
