Revolt · Accepted Answer

(–4, 2)

Question 2

Choose the answer to complete each statement.

Revolt · Accepted Answer

The slope of the line is .: 7/3; The y-intercept is at .: –3; The graph represents the function .: g(x) = (7/3)x–3

Question 3

A class of 24 students is planning a field trip to a science museum. A nonrefundable deposit of $50 is required for the day-long program, plus a charge of $4.50 per student.Determine a linear function that models the cost, c, and the number of students, s.Which statements about the linear function and its graph are correct? Check all that apply.The linear model is f(s) = 4.5s + 50.The linear model is f(c) = 54.5c + 24.The domain is {x| 0 ≤ x ≤ 24}. The range is {y| 50 ≤ y ≤ 158}. The graph is continuous.

Revolt · Accepted Answer

The linear model is f(s) = 4.5s + 50.; The domain is {x| 0 ≤ x ≤ 24}.; The range is {y| 50 ≤ y ≤ 158}.

Question 4
