Question

What is the slope of the line passing through the points (2, 7) and (–1, 3)?

A. 2/7

B. 3/4

C. 4/3

D. 1/3

Answer 1

Slope is given as:
\[\large Slope = \frac{y_2 - y_1}{x_2 - x_1}\]

Answer 2

Here : y2 = 3, y1 = 7, x2 = -1 and x1 = 2..

Plug in the values and solve to find slope..

Answer 3

yeh this is the form for slope just put and get

Answer 4

I failed algebra....I have no idea what to do with that.

Answer 5

I have just given the values, just place them and do the simplification.

Answer 6

Give a try at least.. I will help you where you will go wrong..

Just give a try..

Answer 7

I'll...try, but I;m really bad at math.

Answer 8

Just try else leave on us...!!

Answer 9

leave what on who?

Answer 10

never mind, I'm just going to try the problem.

Answer 11

Hey, you are just talking to me, just plug in the values in place of y2, y1, x2 and x1 there..

Answer 12

ooooooooh! I get it now! Okay, thank you. I'm going to try that, and see what I come up with.

Answer 13

Sure, go ahead..

Answer 14

Wait, now I'm confused again. I remember learning that y2 is like a simple way of saying y * 2, so if it's y * 2, how does it equal 3? I can't seem to think of a number that equals 3 when timesed by 2...

Answer 15

multiplied by 2*

Answer 16

@msinsaneone15 Please read the posts by @waterineyes again.

Answer 17

See, y2 I mean by it is : \(y_2\)..

Answer 18

It is just a variable..

Answer 19

See in more clearer form:
\(y_2 = 3\)
\(y_1 = 7\)
\(x_2 = -1\)
\(x_1 = 2\)

Now use them..

Answer 20

See you have \(y_2\) in your formula too, just place 3 in place of \(y_2\) there in your formula, and similarly do it for all others..

Answer 21

oh! Okay, now I understand. Okay, I was just confused by what you meant by place them. Thank you.

Answer 22

Place??

I mean just substitute them or Plug in the values there..

Answer 23

Oh, okay. I can figure it out from there, thank you!

Answer 24

Just post the answer after solving it so that I can check it..
