Question

What is the slope of the line that passes through the given points? (2,12) and (6,11)
A)-1/4
B) 1/4
C) 4
D) -4

Answer 1

What do you think the answer is? :)

Answer 2

Do you know how to find the slope?

Answer 3

no not really

Answer 4

Well, I can help you with that.
Just give me a second. :)

Answer 5

ok thanks

Answer 6

1. First identify the points on the line.
We are going to do this step-by-step so you don't get confused, :)

Answer 7

Slope formula.

Answer 8

thanks so much

Answer 9

First, identify two points on the line. Then, you could use these points to figure out the slope. In this tutorial, you'll see how to use two points on the line to find the change in 'y' and the change in 'x'. Then, you'll see how to take these values and calculate the slope. So this is basically what you do.
You will need the slope formula: Let (x1, y1) and (x2, y2) be two given points, and let (x, y) be any point on the line. Then the slope joining one of the given points and any point, is equal to the slope joining the two given points, because a line has one and only one slope. This is called the two-point formula for the equation of a straight line. :)

Answer 10

(y2 - y1) / (x2 - x1)

Answer 11

There you go, so.
Do you know what the y2 and y1 would be? :)

Answer 12

isn't it to help find the slope?

Answer 13

You have (2,12) and (6,11).
What are the y's?

Answer 14

Yes, I am helping to find the slope :)

Answer 15

the y's are 2 and 6?

Answer 16

No, those are the X coordinates.
The y's would be 12 and 11.

Answer 17

(x,y) <---That is the order. :)

Answer 18

oh ok

Answer 19

So now, all you have to do is fill in your formula with the coordinates. :)

Answer 20

What would your y1 be?

Answer 21

12?

Answer 22

CORRECT! :D

Answer 23

sweet

Answer 24

Now, let me create an equation, and we can fill in the numbers as we go :)

Answer 25

ok

Answer 26

This is what we got so far.

Answer 27

Now, do you know what our Y1 would be? :)

Answer 28

11

Answer 29

CORRECT AGAIN! :D

Answer 30

We have this so far, now...

Answer 31

Do you know what our X2 would be? :)

Answer 32

6?

Answer 33

CORRECT! :D (AGAIN) LOL

Answer 34

lol

Answer 35

Almost done! :)
We have one more to go.

Answer 36

Do you know what our X1 would be? :)

Answer 37
