Hey there!
y = -1/4x + 10
Looking for the amount of hours of sleep for an 8 year old, so x is 8.
Solve for y:
y = -1/4(8) + 10
y = -2 + 10
y = 8
The predicted number of average hours of sleep for an 8 year old is 3. 8 hours.
Hope this helps!
Replace each letter with it's value, so:
= (5*-2) + (-3*2) + 3
= -10 -6 +3
= -13
