Question

Select the equation of the line that passes through the point (3, -1) and is perpendicular to the line on the graph.

A: y= -1
B: y= 3
C: x= -1
D: x= 3

Answer 1

How did you get that? I've been puzzled with this one for several minutes...

Answer 2

Ok so i use geogebra for this it is a app for the computer and i plug in the point (3,-1)

Answer 3

Oh lol I have geogebra but didn't even think of using it... Wow I feel dumb for not thinking of that sooner...

Answer 4

so after you do that you want the line to pass through (3,-1)

Answer 5

and perpendicular would be across and y=-1 is the only one that goes through 3,-1 and the line goes across

Answer 6

Got it... I got like 2 more of those kinds of problems left... I'm gonna try to use geogebra for them

Answer 7

ok good luck!!

Answer 8

Though this one says Write the equation of the line that is parallel to the line 4x - 3y = -12 and passes through the point (-3, 4).

Answer 9

I dont really get what they mean by that...

Answer 10

ok so then you would plug the equation and the point into geogebra

Answer 11

once both of those are plugged in put all the choices in and now the criteria has to fit both so the line drawn has to be at a 90 degree angle to the line and passing through the point

Answer 12

I got y=-3/4x+8... does that sound right to you?

Answer 13

let me check

Answer 14

no, ok so yes it crosses through the line but it does not pass through the point (-3,4) try plugging in the other choices

Answer 15

Actually hold on one sec I'll try those

Answer 16

ok!
