Question

Which line is parallel to the line that passes through the points (1, 7) and (-3, 4)

Answer 1

the slope of parallel line is same.

use slope formula (y1-y2)/(x1-x2)=(7-4)/(1+3)=3/4.

the slope of given line is 3/4. thus the slope of line parallel to it is also 3/4.
y=3/4x+b
there is no given point though which the parallel line passes. so there are millions of equations:

y=3/4
y=3/4+1
y=3/4+0.9
and so on

Answer 2

woops mistake
y=3/4x
y=3/4x+1
y=3/4x+0.9
and so on

Answer 3

thnx!
