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?
1 answer
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.
