Question

Select the equation of a line that is perpendicular to the line on the graph and passes through the point (3, 2).

Answer 1

Do you know what the original equation is?

Answer 2

Nope.

Answer 3

Mkay, hold on.

Answer 4

Okay, so by looking at the graph I can tell the original equation is y = 3x + 2. Now I just need to find the perpendicular equation.

Answer 5

\[y = \frac{ 1 }{ 3 } x + 3\]\[y = -\frac{ 1 }{ 3 } x + 3\]\[y = 3 x + 2\]\[y = -\frac{ 1 }{ 3 } x + 2\]

Answer 6

Can you explain how you know thats the equation?

Answer 7

Okay.

Answer 8

Look at the graph closely the y intercept is 2... and the slope is 3/1.

Answer 9

The slope form equation is y = m(x - x) so I inserted the slope 3 for m and 2 for the second x.

Answer 10

Okay! that makes perfect sense!

Answer 11

Now we need to find the equation that is perpendicular. To do that we need this equation:
\[y - y _{1} = m(x - x _{1})\]

Answer 12

We were given the points, (3, 2). Where x = 3 and y = 2.

Answer 13

Now I will insert the numbers. y - 2 = 6(x - 3) I am not sure what the slope is so I am using 6. but I will check to see if it is correct.

Answer 14

y - 2 = 6(x - 3)
y - 2 = 6x - 18
+2 = + 2
y = 6x - 16

Answer 15

Now I am going to graph it to make sure it's correct brb.

Answer 16

It is Perpendicular and it passes through (3,2), but is it one of your answer options?

Answer 17

Look up there more. I don't thin it is.

Answer 18

Okay, is this an assignment or test? Also, What do the answer options look like? Are they equations or graphs?

Answer 19

*does

Answer 20

Equations, I posted it up there. It is a test, not an exam.

Answer 21

I don't see any answer options I just see a graph. I used the graph to find both equations. Do you have answer options or do you have to write this down?

Answer 22

\[y = \frac{ 1 }{ 3 }x + 3\]\[y = -\frac{ 1 }{ 3 }x + 3\]\[y = 3x + 2\]\[y = 1\frac{ 1 }{ 3 }x + 2\]

Answer 24

Oh, ok. Hold on.

Answer 25

Hmm.... it doesn't see like any of those pass through (3,2)...

Answer 26

Strange.

Answer 27

Ya, I graphed it. All of them are perpendicular but none of them pass through (3, 2). Let me re-check.

Answer 28

Okay

Answer 29

Okay, it's y = (-1/3)x + 3.... The second one.

Answer 30

I'll send a file.

Answer 31

What do I open that in?

Answer 32

Err, anything you want I guess?....

Answer 33

is it a picture?

Answer 34

Yes, of the graph.

Answer 35

It's just proof, but you don't need it.

Answer 36

Okay. Thank you

Answer 37

Your Welcome.
