Answer:

see explanation

Step-by-step explanation:

so, when a=-3, c is -20. now, to find b when a is -3, plug a (which is -3) into the equation b=4a-5 to get b=-17. so b=-17, c=-20. b is obviously larger (remember the negative sign)

when c is 21, a is 5. plug numbers in to get b=15.

when a is 6, there is no clear value for c, so i'd guess undefined. b however is 19

we can plot the line and the points, for problem 4 and all points above the line means that c is greater than b, and when below it's less than. doing this we get when a is 12, when a is 0, and when a is 5. hope this was clear
