Answer 1

Basically you have to plug these in

I=21

II=9

III=0.5

Answer 2

Basically, you have to plug either the x into the equation to get the y, or the y into the equation to get the x. so:

i = 21

ii = 9

iii = 0.5

Explanation:

The Main Equation : y = 4(x) - 3

i = 4(6) - 3

i = 24 - 3

i = 21

33 = 4(ii) - 3

36 = 4(ii)

9 = ii

-1 = 4(iii) - 3

2 = 4(iii)

0.5 = iii
