Question

Select the correct answer.

Which line is parallel to the line that passes through the points (-1, 2) and (5,-4)?
A. Y=-x+1
B. Y= 1/3 x-4
C. Y= 1/3 x+4
D. Y=x+3

Answer 1

Answer: A

Explanation:

The slope of the line that passes through the given points is
`(-4-2)/(5-(-1))=-1`. Since parallel lines have equivalent slopes, we are looking for a line that also has a slope of -1, which is option A
