1. Question 1
Decide whether the pair of lines is parallel, perpendicular, or neither.
3x - 8y = -13
32x + 12y = 19
a. Neither
Parallel
Perpendicular
Question 2
Find the slope and the y-intercept of the line.
2x + 5y = 24
Question 3
Write a cost function for the problem. Assume that the relationship is linear.
A moving firm charges a flat fee of $40 plus $35 per hour. Let C(x) be the cost in dollars of
using the moving firm for x hours.
C(x) = 35x + 40
C(x) = 35x - 40
C(x) = 40x - 35
C(x) = 40x + 35
Question 4
Evaluate the expression using order of operations.
-10 + (5 ? 3 + 40)
a. Neitherb.
Parallelc.
