Answer 1

The correct answer for the first question is option c) .

The cost of a trip with this driver can be represented as c = 0.65m + 10, where c is the total cost and m is the total miles driven.

Option a) correctly represents the cost of the trip. Option b) represents a linear equation with a slope of 10 and a y-intercept at (0, 0.65), which is not valid for this scenario. Option d) is incomplete and does not accurately represent the cost of the trip.

For the second question, the correct answer is option b) -9.

When x = -4, the corresponding y value is -9. Using the given values in the function, we see that y decreases by 0.70 for every increase of 2 in x. Therefore, when x increases by 6 from 0 to 6, y decreases by 0.70 x 3 = 2.10. So, the value of y at x = -4 would be 10 - 2.10 = 7.9, which is rounded to -9.
