Answer: slope is 3/5
Solution
Rewrite in the form y = a + bx
3. Find the slope of the line segment connecting the following points:
(3,-1) and (-2,5)
Answer: slope is –1.20
x1 = 3 y1 = 1
x2 = - 2
y2 = 5
4. Find the slope of the line segment connecting the following points:
(-1,-1) and (1,3)
Answer: slope is 2
x1 = -1 y1 = -1
x2 = 1
y2 = 3
5. Find the slope of the line segment connecting the following points:
(-4,2) and (1,2)
Answer: slope is 0. The line is horizontal.
x1 = -4 y1 = 2
x2 = 1
y2 = 2
6. Find the slope of the line segment connecting the following points:
