Posted by bianca, pleeease help i'm lost on .
Eq 1 y = 2x + 3
Eq 2 y = 2x + 1
How can you determine these are parallel? Can you graph both equations? Is it possible the lines do intersect somewhere away from the coordinates you are plotting?
the equation of line is y=mx+c where m is the slope of the lines i.e inclination on x axis . since both the lines have the same slope i.e 2, they r parallel to each other.
