Answer
Option C
y = 3x
The equation that best represents the relationship between x and y
Step-by-step explanation
We are asked to find the equation that best represent the relationship between x and y, to do this, we need to note that ordered pairs are written as (x, y)
(3, 9)
(6, 18)
(7, 21)
(10, 30)
So, testing each of the equations given, we will pick the one where all the answers match
Option A
y = x^2
when x = 3, y = 3^2 = 9
when x = 6, y = 6^2 = 36 which is not equal to 18
Option B
y = 4x - 7
when x = 3, y = 4(3) - 7 = 12 - 7 = 5 which is not equal to 9
Option C
y = 3x
when x = 3, y = 3(3) = 9
when x = 6, y = 3 (6) = 18
when x = 7. y = 3(7) = 21
when x = 10, y = 3(10) = 30
We can see that all the answers match the answers obtained.
Hope this Helps!!!
