Graphing Data

• The Age is the X-value.

• The Height is the Y-value.

• The ordered pairs plotted on this graph are (1, 30) (2, 35) (3, 38) (4, 41) (5, 44)

• Therefore this graph represents Ryan's height increasing as his age increases.

Graphing Data

• The Day is the X-value.

• The Height is the Y-value.

• The ordered pairs plotted on this graph are (5, 1) (10, 3) (15, 8) (20, 12) (25, 16)

• Therefore this graph represents the height of the plant increasing over time.

Open Ended

Write the ordered pairs to show the relationship between the month and the weight of a bird.

Open Ended

What do you think would happen to the bird’s weight over the next four months?

On a seperate sheet of paper graph the data correctly.

Open Ended

Describe the error Mary made.

Where do you think the miniature car will stop? Write the ordered pair. Explain your answer.

Multiple Choice

The graph shows the relationship between the length of an eruption of Old Faithful, x, and the length of time until the next eruption, y. Which of these ordered pairs is on the graph?

• $\left(95,\ 5\right)$

• $\left(2,\ 50\right)$

• $\left(70,\ 3\right)$

• $\left(4,\ 80\right)$

Multiple Choice

Which set of ordered pairs shows the data in the table?

• $\left(1,2\right)\left(3,4\right)\left(5,3\right)$ $\left(9,13\right)\left(17,20\right)$
  

• $\left(1,3\right)\left(2,9\right)\left(3,13\right)$ $\left(4,17\right)\left(5,20\right)\$

• $\left(20,5\right)\left(17,4\right)\left(13,3\right)$ $\left(9,2\right)\left(3,3\right)$

• $\left(1,3\right)\left(9,2\right)\left(13,3\right)$ $\left(4,17\right)\left(20,5\right)$

Multiple Choice

Sean is growing a plant in a jar. He makes a graph to show the days since he put the seed in the jar, and the length of the longest root (in centimeters). He first sees the root in 4 days, and he writes the ordered pair (4, 2). Three days later, the root measures 18 cm. Five days later, it has grown another 25 cm. What ordered pairs does Sean add to his graph?

• $\left(7,18\right)\left(12,43\right)$

• $\left(18,3\right)\left(25,5\right)$

• $\left(3,18\right)\left(5,25\right)$

• $\left(18,7\right)\left(43,12\right)$

Multiple Choice

Marie was in fifth grade when she began to record her baby sister’s height and her own height in inches every six months for 3 years. She plots the data on a graph where the x-coordinate represents her sister’s height and the y-coordinate represents Marie’s height. Which ordered pair could NOT be on the graph?

• $\left(24,\ 51\right)$

• $\left(33,\ 60\right)$

• $\left(55,\ 30\right)$

• $\left(28,\ 52\right)$
