Question

Three points of a function are graphed. A coordinate plane with 3 points plotted at (10, 18), (14, 24), and (18, 30). Which statement describes the function through the points?

Answer 1

Answer:

The correct answer is The function is a direct variation function with a constant of variation 1.5

Step-by-step explanation:

One way to see if this is a linear function is to see by how much the x and y increase each time:

x   |  y

10 | 18

14 | 24

18 | 30

X is increasing by 4 each time, and y is increasing by 6. This is a linear function. Divide the y by the x to get the slope.

6 ÷ 4 = 1.5

This is a linear function and its slope is 1.5.

Hope this helps,
