Question

I have a few questions involving Parallel and perpendicular lines. Any help is greatly appreciated!


Tell whether the lines for each pair of equations are parallel, perpendicular, or neither.

3x - 5y = 3
-5x + 3y = 8

Tell whether the lines for each pair of equations are parallel, perpendicular, or neither.

7x – 4y = 4
x – 4y = 3

Are the graphs of the lines in the pair parallel? Explain.

y = -1/9x + 20
x + 9y = –9



Tell whether the lines for each pair of equations are parallel, perpendicular, or neither.

y = -7/2x + 1
6x – 21y = 24

Answer 1

First solve all of those equation and put them in y=mx+b form.

Next You'll need to note the following
Parallel Lines have the same slope
Perpendicular Lines have negative inverse slopes
