Answer:
Find the slope of the line that passes through the pair of points. (–5.5, 6.1), (–2.5, 3.1) 
Use the slope formula to find the slope m . 
m = − 1
Explanation:
The slope is 
m 
= 
− 
1 
 
Explanation: 
The slope can be found by using the formula: 
m 
= 
y 
2 
− 
y 
1 
x 
2 
− 
x 
1 
 
Where 
m 
 is the slope and ( 
x 
1 
, 
y 
1 
) and ( 
x 
2 
, 
y 
2 
) are the two points on the line. 
 
Substituting the values from the points in the problem gives: 
 
m 
= 
3.1 
− 
6.1 
− 
2.5

− 
5.5 
= 3.1 − 6.1 − 2.5 + 5.5 = − 3/ 3 = − 1

,(6.1-3.1)/(-5.5-2.5) = 3/-8 = -3/8=-.375

ANSWER 
The slope is 
 
 
 
EXPLANATION 
 
The slope of the line that passes through, 
 
 
can be found using the formula, 
 
 
 
So we let, 
 
 
 
and 
 
 
 
 
We substitute them into the formula to get, 
 
 
This gives us, 
 
 
We simplify to get, 
 
 
 
 
slope = -1
