Grade 9 Math: Linear Relations and Equations Parallel Lines and Perpendicular Lines

a line that intersect another line at a 45 degree angle

a line that intersect another line at a 90 degree angle

a line that intersect another line at a 30 degree angle

a line that intersect another line at a 15 degree angle

Parallel lines are lines on a plane that meet

Parallel lines are lines are conjoined together

Parallel lines are lines that do not exist

Parallel lines are lines on a plane that never meet. They are always the same distance apart.

True

False

$$y=7x+6$$

$$y=\frac{-1}{7}x+6$$

$$y=7x-6$$

$$y=7x$$
