Identical Lines fposter,small,wall_texture,product,750x1000

Infinite Solutions

Same Slope, Same y-intercept

Choose any (x,y) along the line

Parallel Lines examples-of-parallel-lines

Parallel lines never intersect

Same Slopes

No Solution

Intersection at (x,y) intersecting-lines-1626085514

This (x,y) makes all the equations true

(x,y) is the solution
