Is AB parallel to CD?

Mathematics
1 answer:
Katen [24]3 years ago
6 0
You have to evaluate the slopes of these lines. For line AB you have a slope of
\frac{1 - ( - 3)}{0 - ( - 3)}  =  \frac{4}{3}
For line CD you have a slope of
\frac{ - 1 - ( - 5)}{3 - 0}  =  \frac{4}{3}
Because the slopes are equal and the two lines are not one and the same, they are parallel.
