Question

1. What is the slope of the line that passes through the points (-2, 5) and (1, 4)?

Answer 1

1. (-2,5)(1,4)
slope = (4 - 5) / (1 - (-2) = -1 / 3

2. (11,13)(8,18)

3. (6,y)(10,-1)
    slope = (-1 - y) / (10 - 6) = (-1- (-2) / 4 = 1/4
     y = -2

4. undefined

5. (2,110)(3,165)
     slope = (165 - 110) / (3 - 2) = 55/1 
     this basically means that to rent a charter boat, it will cost 55 per person
