Question

Barack went to amusement park for enjoying rides. The scatterplot shows possible amount of his expenses .The equation of the best fit line is $y=3x+8$. What does $3$ in the equation represent?

• A. The cost of one ride
• B. The number of rides Wesley rode
• C. The cost of the admission ticket
• D. The number of hours Wesley stayed at the park

Answer 1

The correct option is A The cost of one ride

$y=3x+8$

When $x=0y=8$

Initial money(cost)=8

Here,3 is slope of line.

$y=3x+8$

We can say $y$ is changing by $(3x+7)$

So, 3 is cost of one ride.
