Question

(b) Paul uses the function y = 8x + 40 to model the situation. What score does the model predict for 3 h of homework? Assuming that is the amount of hours spent doing homework: Y=8(3) + 40. Y= 64 That means that since a value is the test score (because that's what the y-axis is labeled), your predicted test score is a 64.

(c) What does the number 40 in Part (b) mean in the context of the situation?

Answer 1

where is the graph you speak of?

Answer 2

The number 40 is the y-intercept, or what 'y' is when 'x' is 0. So if you study for 0 hours, your predicted test score is a 40%.
