Here are the equations of 12 straight lines.
These 12 straight lines can be divided up into six pairs, each pair matching one of the following descriptions:
These lines are parallel.
These lines are perpendicular.
These lines have the same \(y\)-intercept.
These lines have the same \(x\)-intercept.
These lines both go through the point \((1,5)\).
These lines …
Can you sort them into the correct pairs and complete the final description?
Note that the \(x\)-intercept of a line is where the line crosses the \(x\)-axis.
