Jack plots points showing equivalent ratios on the coordinate plane above. which ordered pair if plotted above would represent a ratio that is equivalent to those shown?

(4,18)

Step-by-step explanation:

it would fit right into the line. i hope this helps.

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
