Question

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

y=-4x + 3

-2x+8y=5

Please help!

Answer 1

my first idea is to convert -2x+8y=5 to a slope intercept form equation

Answer 2

Start by getting the lines in slope-intercept form \(\large y=mx+b \)

Then look at the slope \(\large \color{red}{m} \)

Answer 3

yea~ xD that was my idea

Answer 4

ok i do not know how to do that

Answer 5

If the slopes are identical, then they are parallel.
If the slopes are negative reciprocals of each other, then they are perpendicular.

Answer 6

so all i have to do is find the slope?

Answer 7

ok thanks bye

Answer 8

lol I'm taking flvs and I just talked to my math teacher and the password for 4.00 was slope xD
