Question

Find the slope of the line that passes through (1, 8) and (8, 7).

Answer 1

Answer: -1/7
Step by step:
7-8=-1
8-1=7

Answer 2

(-1/7)

Explanation:

you can consider (1,8) as x1 and y1 respectively.

and then consider (8,7) as x2 or y2 respectively.

then apply formula y2-y1/x2-x1 .

that will be 7-8/8-1 .

after solving you'll get -1/7
