Question

Percy is plotting points on a graph. The ratio of y -value to x -value is 2 to 3 for each point. What will be the x -value of a point with a y -value of 18 ?

Answer 1

27 because the unit rate is 2/3, and 2/3 of 27 is 18

Answer 2

x= 27

Explanation:

Percy is plotting points on a graph.

The ratio of y -value to x -value is 2 to 3 for each point

Ratio of y to x is 2 to 3

`(y)/(x) = (2)/(3)`

Given y value is 18

lets find out x

`(y)/(x) = (2)/(3)`

Plug in 18 for y

`(18)/(x) = (2)/(3)`

Cross multiply it

3*18 = 2x

54= 2x

Divide by 2 on both sides

x= 27
