Question

What is the slope of the line shown below
A. -2/7
B. 2/7
C.-7/2
D.7/2

Answer 1

Answer: The slope of the line is choice A,
`-(2)/(7)`

Explanation:

First, plug in the coordinates into the slope formula:

m =
`(y_(2)- y_(1) )/(x_(2-) x_(1) )`

m =
`(1 - 3)/(3 - (-4))`

Simplify:

m =
`(1 - 3)/(3 - (-4))`

m =
`(-2)/(7)`

m =
`-(2)/(7)`
