Question

Is it possible for two linear functions whose graphs are parallel lines to have the same y-intercept?explain.

Answer 1

No. If they had the same y intercept, they'd be the same line. They would have to be perpendicular to have the same y intercept.

Answer 2

No. It's not possible. Parallel lines have the same slope. If the two lines have the same slope and also the same y-intercepts then they are the same line, not two different lines.

Answer 3

ok thanks so much!!!!!

Answer 4

You're welcome :3

Answer 5

Another way to think about it

if the two lines have the same y-intercept, then they must cross at at least one point (this one point -- the y-intercept) ... but parallel lines never cross or intersect

so it's not possible for two lines to be parallel and have the same y-intercept

Answer 6

Ok thanks again! (:
