Question

Find the Slope of the line through points:

(-3,-4) and (16, 8)

Answer 1

There is a special formula for this, do you know what it is?

Answer 2

Wouldn't the steps be to do:

Y2 - Y1

Over

X2 - X1

Answer 3

Yes great!

Answer 4

That part I do know, but it's the part that comes after I'm not so sure of

Answer 5

So now you can just pick which ever points you wan as Y2 X2 and so on

Answer 6

Is the answer always supposed to be a fraction?

Answer 7

technically not

Answer 8

for example if you get 10/5 the slope might end up being 5 which would technically be 5/1 in rise over run form. Making 5 rise and 1 run

Answer 9

I'm sorry the slope will end up being 2*

Answer 10

oh, I forgot I was supposed to simplify

Answer 11

always, but when you graph the fraction even if you get slope 4 for example you would still move 1 to the right. Did i answer your questions?

Answer 12

Yes you did. Thank you!

Answer 13

No problem!

Answer 14

Just one last thought, but it is common for the rise to be negative sometimes right?

Answer 15

yes, but when your simplifying the slope form, if the rise is negative the whole slope is negative just like when the run is negative the whole slope is negative

Answer 16

I see

Answer 17

basically the rise cannot be negative and the run is positive, if one is negative they are both negative

Answer 18

or vise versa

Answer 19

Ahh, I see it now. Thank you

Answer 20

No problem
