Question

Please help i’ll mark as brainliest. Even if you can only answer one its ok. 3. Without graphing how will you know if the graph is a set of parallel lines? Intersecting lines? Lines that coincide? 4. What do graphs indicate about the values of the variables in the system? 5. In what way can your understanding of graphs of systems of linear equations help you in determining the most favorable options in life?

## Answers ( )

Answer:by slope of given eq

for parallel line slope are same

for intersection line slope are different

Parallel and Perpendicular Lines. When you graph two or more linear equations on the coordinate plane, they usually intersect at some point. However, when two lines in a coordinate plane never intersect, they are called parallel lines.
