Graphing on Coordinate Plane

Ms. Williams noticed that the lack of rain was impacting the growth of her tomato plants.

● Every week, she recorded data in sets of ordered pairs.

● The x-coordinate is the number of weeks at the time of recording.

● The y-coordinate gives the height of the plant in inches.

She recorded the following coordinates for a plant exposed to pollution:

(1, 3), (2,9), (3,14), (4,18), (5, 21)

If the pattern continues, at which week should Ms. Williams expect no change in the plant height? Hint: Record the data into a table.

• Week 7

• Week 8

• Week 9

• Week 10

Between which two years did the bear population remain constant?

• 2000 and 2001

• 2002 and 2003

• 2004 and 2005

• 2003 and 2004

A student graphs a point on a coordinate plane that represents the ordered pair (0,7). Which describes the location of the point on the coordinate plane?

• The point is located 7 units above the x-axis.

• The point is located 7 units to the right of the y-axis.

• The point is located on the origin of the coordinate plane.

• The point is located on the x-axis.

The ordered pairs represent the location of four people. Choose the correct answer from each drop-down menu to complete the statement. Eddy is located ​ (a)   west and ​ (b)   south of Ivan.

• 9 units

• 4 units

• 8 units

• 7 units

• 5 units

• 6 units

A line segment has been drawn on the coordinate plane. Which ordered pairs are below the line segment? Select three correct answers.

Four points have been plotted in the coordinate plane. Which statements are true? Select two correct answers.

• Point A has a y-coordinate of 2.

• Point B is located on the origin of the coordinate plane.

• Point C is located on the y-axis.

• Point D has an x-coordinate of 7.

A student will graph the ordered pair (3,8) on a coordinate plane. Which steps can the student take to graph the point correctly?

• Start at the origin. Move 3 units to the right. Move 8 units up. Graph the point.

• Start at the origin. Move 3 units up. Move 8 units up. Graph the point.

• Start at the origin. Move 3 units up. Move 8 units to the right. Graph the point.

• Start at the origin. Move 3 units right. Move 8 units right. Graph the point.

The points on the coordinate plane represent a numerical pattern. Which statement about the pattern is true?

• It is a multiplicative pattern because each x-coordinate is multiplied by 7 to create the corresponding y-coordinate.

• It is an additive pattern, because each x-coordinate is increased by 5 to create the corresponding y-coordinate.

• It is a multiplicative pattern, because each x-coordinate is multiplied by 6 to create the corresponding y-coordinate.

• It is an additive pattern, because each x-coordinate is increased by 6 to create the corresponding y-coordinate.

Four points have been plotted on the coordinate plane. Which statements are true? Select three correct answers.

• Point A is located 5 units above the x-axis.

• Point B is located 2 units above the x-axis and 9 units to the right of the y-axis.

• Point C is located 3 units above the x-axis and 4 units to the right of the y-axis.

• Point D is located 6 units above the x-axis.

• Point E is located 2 units above the x-axis and 9 units to the right of the y-axis.

Which statements about a coordinate plane are true? Select two correct answers.

• The ordered pair (0,0) represents the origin of a coordinate plane.

• The horizontal line on a coordinate plane represents the y-axis.

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

• The vertical line on a coordinate plane represents the y-axis.
