is this equation parallel , perpendicular or neither

Question

 

11) y = 1/4x - 3

5y = 20x + 5

A) parallel B) perpendicular C) neither

Answer 1

y = (1/4)x - 3

5y = 20x + 5

y = 4x + 1

.

1/4 is different than 4, so the slopes are different, so the lines aren't parallel.

1/4 and 4 have the same + or - sign (+ in this case), so the lines aren't perpendicular.

Answer:  C) neither
