A. -3
B. -2
C. -1/3 **
D. 1/3

2. A line has a slope -5/3. Through which two points could this line pass?
A. (12, 13) and (17, 10)

C. (0, 7) and (3, 10)
D. (11, 13) and (8, 18) ***

D. 5

4. What is the slope of the line that passes through the points (4, 2) and (4, -3)?
A. -1
B. 0
C. 1
D. Undefined ***

Answer 1

(4-5)/(1+2) = -1/3 yes

(18-13)/(8-11) = -5/3 yes

(1-y)/(10-6) = 1/4
1-y = 1
y = 0 Huh? typo?

(-3-2)/0 = undefined
