Answer 3

look at the equation for midterm score :
\[\large y=\color{blue}{3.84}x+\color{purple}{15.64}\]


can you tell what quantity the variable \(x\) represents here ?

Answer 4

Hours? @rational

Answer 5

Yes, \(x\) represents hours spent studying

what about \(y\) ?

Answer 6

The score? @rational

Answer 7

Yes, what does \(\color{blue}{3.84}\) represent here ?

Answer 8

since you're multiplying \(x\) by \(\color{blue}{3.84}\), the score increases by this amount for every 1 hour increase in study hours

Answer 9

so \(\color{blue}{3.84}\) is the answer for part a
