Question

The trend line for the data is y = -7.2 x + 98.9 intercept the y-intercept what is the average grade if the student was on social media for 0 hours

Answer 1

If a student was on social media for 0 hours, then the x value in the equation would be 0. Plugging this into the equation y = -7.2x + 98.9, we have:

y = -7.2(0) + 98.9
y = 98.9

Therefore, the average grade if the student was on social media for 0 hours would be 98.9.
