Question

if a system of equations has no solution, what does the graph look like?
1 skew lines
2 parallel lines
3 intersecting lines
4 intersecting lines

Explanation:

A system of linear equations with no solution means the lines representing the equations never meet. Skew lines are in 3D and not relevant here. Intersecting lines have one solution. Parallel lines (in 2D) have the same slope and different y - intercepts, so they never intersect, meaning no solution.

Answer:

1. parallel lines
