Question

What is the slope of line CD?
A. -4/1
B. 4/1
C. -1/4
D. 1/4

Answer 1

Simple...

we can see the line hits a coordinate at (5,-2) and also at (7,6)

You could use $\frac{ y_{1}- y_{2} }{ x_{1}- x_{2} }$->>to find its slope

$\frac{-2-6}{5-7} = \frac{-8}{-2}$

m=4 (B)

This means that if you go on your line..start at (5,-2) and go up 4 and over 1 it should hit (6,2)..does it hit? YES.Then you know your are correct.

Thus, your answer.
