Question

Sindy surveyed a group of students. The table represents the hours, h, they spent studying and their scores, s.What does the slope of the trend line equation s = 32.4h + 302.6 represent? For an increase of 1 h in study time the test score will increase by approximately 302.6.For an increase of 302.6 h in study time the test score will increase by approximately 1.For an increase of 32.4 h in study time the test score will increase by approximately 1.For an increase of 1 h in study time the test score will increase by approximately 32.4.

Answer 1

`s=32.4h+302.6`

The slope of the trend line is 32.4, and it represents the change of s per 1 hour.

Then, as the slope is 32.4 it represents: For an increase of 1 h in study time the test score will increase by approximately 32.4
