# 5.05 Proportional relationships in the coordinate plane

## Interactive practice questions

The ratio of $x:y$x:y is $1:2$1:2 and is represented in the table of values below.

 $x$x $y$y $3$3 $4$4 $5$5 $6$6 $6$6 $8$8 $10$10 $12$12
a

We want to plot the points from the table of values. First plot the point $\left(3,6\right)$(3,6) on the plane.

b

Plot the point $\left(4,8\right)$(4,8) on the plane.

c

Plot the point $\left(5,10\right)$(5,10) on the plane.

d

Plot the point $\left(6,12\right)$(6,12) on the plane.
