Answer 1

As the x values increase, the y-values increase — False
- The scatter shows fuel efficiency decreasing as weight increases (negative relationship), so y does not increase with x.

This is a proportional relationship — False
- The points do not lie on a line through the origin, so it is not proportional.

The weight and fuel efficiency show a strong, negative correlation — True
- Heavier vehicles have noticeably lower fuel efficiency, indicating a strong negative correlation.

The line of best fit does not have to hit any of the data points, would have a negative m and a positive b — True
- A best-fit line need not pass through points; here the slope would be negative and the y-intercept positive.

The y-intercept for the line of best fit would be around (0, 2400) — False
- A y-intercept of 2400 is unrealistic for fuel efficiency; the intercept would be a much smaller positive number (mpg).
