Now use the information you already have about finding the equation of a line and apply it to the dashed lines shown in these triangles. Remember, to find the equation of a line you need a point ...

Parallel lines are a fixed distance apart and will never meet, no matter how long they are extended. Lines that are parallel have ... perpendicular to \(y = 2x + 1\) would be \(y = -\frac{1}{2}x ...
