ok ty

Anypne help with this?

Do you know how to use substitution or elimination?

Put it into slope intercept form first, and if the slopes are the same then it is parallel and if the slopes are opposite-reciprocals of each other then it is perpendicular

I forgot how to put it in slope intercept lol

wait

slope intercept

so for the first function divide everything by 3 to make it y=4x+15 /3

that gives me a decimal tho

the slope on both would need to be the same so that would be 4x/3

put it in fraction. My answer is perpendicular but I rushed it

so y=4x+5
3

12y=12-9x

y=1- (3x/4)

for the second

I just have to find if they are parallel perp or neither

imma be teaching you nothing here, but you can double check your work via desmo

they arent because the first has a slope of 4x/3 and the second has a slope of 3x/4

so perpendicular?

Yes

ok ty

What about this one?

Neither

How did you find that

isolate y

ah

Ah might as well get finish it off with help

Parallel

ok ty guys

Bc the slope is the same

Perpendicular would be opposite reciprocal.

Ex: 1/2 to -2/1

Also use photo math or desmos and it will graph it out

Hey

I need some people to potentially do my corse work for me as I’m currently in bed felling Ill I’ll happily pay £20 a hour for people to do it for me

You know whats really smart for a school to do?
