Graphing Review

By Jade Pinnock

These tables describe the relationship between two numbers X and Y. For example, if Y = 2x

This means if X = 2 then Y=4 because 2 x 2 = 4​

​X-Y Table

​x	​y=2x
​2	​4
​3	​6
​4	​8

Multiple Choice

A pet store owner will order dog beds for his shop. The relationship between x, the number of boxes he will order, and y, the number of dog beds he will receive, can be represented by the equation y = 12x. Which table contains only values that represent the equation?

You are using multiplication to find X or Y

Multiplicative

You are using addition to find X or Y

Additive

Sometimes X-Y tables show an addition relationship or a multiplication relationship

Multiple Choice

• The pattern is multiplicative, because the y-values are 1.5 times the corresponding x-values.

• The pattern is multiplicative, because the y-values are 6 more than the corresponding x-values.

• The pattern is additive, because the y-values are 1.5 times the corresponding x-values.

• The pattern is additive, because the y-values are 6 more than the corresponding x-values.

Multiple Choice

Which table of values does NOT represent y = x + 4.5?

REMEMBER: ​(X,Y)

x is the RUN

y is the rise​

​

(x,Y) Coordinates

x to the left

y to the sky​

Jim plotted the following ordered pairs on a coordinate grid.

(1, 3) (3, 6) (7, 6) (9, 3)

Multiple Choice

Yvonne is using a coordinate grid for the first time. She wants to find the location of the ordered pair (3, 7) on the grid. Starting at the origin, which movement should Yvonne do first?

• Move right along the x-axis to 3

• Move up along the y-axis to 3

• Move right along the y-axis to 7

• Move up along the x-axis to 7

Multiple Choice

A table of ordered pairs is shown. Which graph best represents the ordered pairs?
