Question

What is the slope of the line through the points (-2, 4) and (-1, -1)? m = _?_

Answer 1

slope of the line through the point (x1,y1) and (x2,y2) can determined as
m = (y2 - y1)/ (x2-x1)

Answer 2

And how would you plug that in?

Answer 3

@niksva

Answer 4

x1 = -2, y1=4 , x2= -1 , y2 = -1
just plugin these values and determine slope

Answer 5

Label one of the points number 1 with coordinates $$x_1$$ and $$x_2$$

and the other as number 2 with coordinates $$x_2$$ and $$y_2$$

and then substitute into the equation: $$m = \frac{(y_2 - y_1)}{ (x_2-x_1)}$$

Answer 6

@skullpatrol Would it be 5/3 ?

Answer 7

But I did, (-1-4)/(-1-2)

Answer 8

Sorry :( I got distracted ... you are correct.

Answer 9

Lol it's fine, thanks!

Answer 10

So then the value of the slope is 5/3, correct?

Answer 11

@Mertsj @hartnn

Answer 12

Yes 5/3 is right.

Answer 13

Thank you!

Answer 14
