Coordinate Graphs

Jonathan created a pattern by multiplying each x-coordinate by 2 to get the y-coordinate. What are TWO points on the coordinate that follow this pattern?

The table represents a relationship between x and y.

The relationship between the x-values and the y-values creates a pattern that is--

• additive, because each x-value increases by 5

• additive, because each y-value is determined by adding 17 to the corresponding x-value

• multiplicative, because each y-value is determined by multiplying the corresponding x-value by 17

• multiplicative, because each x-value is a multiple of 5

Customers at a gift shop recieve free stickers for every T-shirt they buy. The graph shows the relationship between x, the number of T-shirts customers buy, and y, the number of stickers customers receive.

Which statement is NOT true about a coordinate grid?

• The vertical number line is the y-axis.

• In a coordinate grid, the x-axis and the y-axis are perpendicular to each other.

• The x-coordinate is the second number in an ordered pair.

• The origin is the intersection of the x-axis and the y-axis.

The table shows a relationship between x and y.
