Question

Write the slope-intercept form of the equation for the line.

Answer 1

Hello,

Your graph is in a positive trend. You can use the rise over run method to obtain the slope-intercept form equation. Do you know how to do this?

Answer 2

Not really. I've forgotten how. I'm mainly confused because the two numbers that are on the graph aren't present in any of the answers and I'm really confused.

Answer 3

Okay, what is the y-intercept of the graph? Do you know how to derive that from the graph?

Answer 4

I originally thought the y-intercept was -4 but now I feel it is -1

Answer 5

Correct. The y-intercept is \(-1\) due to the line intercepting the y-axis at \(-1\).

So that tells us answer choice B is incorrect.

Now do you know how to find the slope of a graph?

Answer 6

No, I do not.

Answer 7

Okay, rise over run does that ring any bell?

Answer 8

Vaguely. Isn't that just, like, the name for how to find a point on a graph? Like, the first number in a point is when you go up and then the second number in the point is when you go over?

Answer 9

I'm sorry, I'm just terrible at math and there's many reasons why I've never been able to pay attention to any information provided to me for math haha.

Answer 10

Okay, start at the lower point and count up to the line of the next point. What number did you count to?

Answer 11

6

Answer 12

Now, count from where your finger is. (Six points above the lower point.) Across to the next point. What number did you count?

Answer 13

1

Answer 14

Are you sure, recount. Remember you rise up six to get to the \(y\) level of the higher point, now count how much you have to run to get on top of the higher point from the rise point.

Answer 15

Wait..I'm confused now. Wait, would it be 2?

Answer 16

OH WAIT. IS IT 3?

Answer 17

You are correct at 2. http://snag.gy/WH1pT.jpg

Answer 18

\[Slope = \dfrac{Rise}{Run}\]
\[Slope = \dfrac{6}{2} = 3\]

Slope-intercept form = \(y = mx + c\)
Where \(m\) is your slope, and \(c\) is your y-intercept.
So input your values into that form.

Answer 19

So..I just insert the 3 and -1 into the right spots? And then the whichever option equals 6, is my answer? O.o

Answer 20

Yes.
You got \(3\) as your slope, and \(-1\) as your y-intercept.

Answer 21

So..Let's try out answer 1, which is y = -3 - 1.
It would be y = -3(3) + 1? Because wouldn't the -1 turn positive?

Answer 22

Incorrect. You do not plug it into your given equations, but into the slope-intercept form equation.
Which is: \[y = mx + c\]

Answer 23

so..y = 3x - 1?

Answer 24

Correct.

Answer 25

that is the final answer, right? and I think I understand more of how to solve this type of problem, so thank you for that :)

Answer 26

You are welcome.

Peace.

Answer 27

I am confused with this question..Could you possibly help with this?

Answer 28

Remember rise over run: http://snag.gy/NgTYV.jpg

Answer 29

@brandonfrabel understand?

Answer 30

y = -1/3 + 3?

Answer 31

Or would the final answer just be -1/3?

Answer 32

The graph is going upwards from left to right, that means the slope must be positive.

Answer 33

ohh..So the final answer is 1/3?

Answer 34

Correct.
