Tell me the answer please. Give me a short answer and a step-by-step explanation.

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!
