Ihave either 1 or 2 attempts to get it

You just have to make equal fractions, so if c = 4 that means = so cross multiply to get 7a = 20; divide both sides by 7 to get a = 2.86 and do the same with the other ones

If c = 11 then = cross multiply to get 7a = 55; divide both sides by 7 to get a = 7.86 and so on

The answer is true to the other question

Hope this helps :)

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)
