Question

Find the slope of the line that contains the following ordered pairs. Show all work
(4, 2) and (7, 6.5) | (10, 8) and (-5, 8) | (1, -3/4) and (4, -3) | (18, -70) and (18, 2) |

Answer 1

Answer:

1). A (4, 2), B (7, 6. 5)

slope of AB=y2-y1/x2-x1

AB=6.5-2/7-4

=4. 5/3

=1. 5 ans

2). P (10, 8), Q (-5, 8)

PQ=8-8/-5-10

PQ=0/-15

=0

3). C (1, -3/4), D (4, -3)

CD=(-3+3/4)/4-1

=-9/3=-3

4). R (18, -70), S (18, 2)

slope of RS = 2+70/18-18

=72/0
