I GIVE MEDALS AND FAN :D Graph with a line going through points zero comma two point five and four comma two point five. Select the equation of the line that passes through the point (3, -1) and is perpendicular to the line on the graph. y = -1 y = 3 x = -1 x = 3

OpenStudy (anonymous):

Can you attach a picture of what you're looking at?

OpenStudy (anonymous):

Always remember that X goes before Y in the alphabet, and it does the same in math too!

OpenStudy (anonymous):

No I don't know how :/ @IronicallyRose but, I described it

OpenStudy (anonymous):

Okay :) @HailKK

OpenStudy (anonymous):

That's okay, I'll try my best. So, what is the slope of the line on the graph?

OpenStudy (anonymous):

You can take a screenshot with a mac by holding shift command 3, and a selective screenshot with shift command 4. What computer are you using?

OpenStudy (anonymous):

^^It's an old panasonic :/ i can't take screenshots. @HailKK & @IronicallyRose let me see hold on

OpenStudy (anonymous):

0

OpenStudy (anonymous):

be right back

OpenStudy (anonymous):

Okay

OpenStudy (anonymous):

So it's either horizontal or vertical?

OpenStudy (anonymous):

It's horizontal

OpenStudy (anonymous):

Oh sorry I didn't put it in the describtion on the graph!

OpenStudy (anonymous):

Okay, that means that the equation of the line is going to be y=?

OpenStudy (anonymous):

Do you think you could figure out what the equation of this line is?

OpenStudy (anonymous):

I dunno :/ Would it be y=0 or something?

OpenStudy (anonymous):

Just find out where it intersects the y axis.

OpenStudy (anonymous):

As for the final answer, we know that we can eliminate the first 2, because in order for the line to be perpendicular, in will need to be x=?

OpenStudy (anonymous):

Okay

OpenStudy (anonymous):

would the answer be x=3?

OpenStudy (anonymous):

Yep!

OpenStudy (anonymous):

Did you understand why?

OpenStudy (anonymous):

Ummm well I knew it wasn't negative

OpenStudy (anonymous):

And x=-1 would not have passed through (3,-1).

OpenStudy (anonymous):

Ohh got it! Thanks!!!!

OpenStudy (anonymous):

Of course! Thank you for the medal and the fan! :)
