Question

create a scatter plot for the set of data.

x	y
3	9
5	12
7	15
9	18

choose the scatter plot on the right.
options: a, b, c, d (with corresponding scatter plot graphs)

Explanation:

Step1: List data points

The data points are $(1,6)$, $(3,9)$, $(5,12)$, $(7,15)$, $(9,18)$.

Step2: Match to correct plot

Check each plot:

• Plot A: x increases right, y increases up; points align with $(1,6)$, $(3,9)$, $(5,12)$, $(7,15)$, $(9,18)$.
• Plot B: y-axis max is 10, cannot fit $y=15,18$.
• Plot C: x-axis max is 10, y-axis max is 20, but points are reversed (x values map to high y, low x maps to low y incorrectly).
• Plot D: x-axis goes to 20, y-axis to 10, cannot fit $y=15,18$.

Answer:

A. <The scatter plot with x-axis 0-10, y-axis 0-20, plotting points (1,6), (3,9), (5,12), (7,15), (9,18)>
