Question

the table of values below shows data for a five-word spelling test.

number of letters vs. percentage who spelled correctly

word	number of letters in the word	percentage of students who spelled the word correctly
2	9	12
3	5	73
4	6	59
5	8	27

which describes how the data for word 2 should be plotted on a coordinate grid?

• from the origin, go 2 units to the right and 9 units up.
• from the origin, go 2 units to the right and 12 units up.
• from the origin, go 9 units to the right and 12 units up.
• from the origin, go 12 units to the right and 9 units up.

Explanation:

Step1: Identify variables for plotting

The x - axis should represent the number of letters (independent variable), and the y - axis should represent the percentage of students who spelled correctly (dependent variable). For word 2, the number of letters is 9, and the percentage is 12.

Step2: Determine the plotting direction

To plot the point, we move along the x - axis (horizontal) first. So we go 9 units to the right (since x - value is 9) and then 12 units up (since y - value is 12) from the origin.

Answer:

From the origin, go 9 units to the right and 12 units up.
