Answer 1

where is question?

Answer 2

The link in the question.

Answer 3

oh.ok.

Answer 4

Well the line is going up so it isn't going to be negative

Answer 5

So C. isn't our answer

Answer 6

OK. I assume it's probably A but I don't know how to actually get the answer.

Answer 7

Find the intersecting point on the y axis and count upp # of units and over # of units the rise over run is your slope :)

Answer 8

Now let's look at this point on the line http://prntscr.com/6izlab (0, -3)

Answer 9

Now let's go to the next point up, http://prntscr.com/6izlg2 (1, 0)

Now how many points do you go up from (0, -3) to even up with (1, 0)? http://prntscr.com/6izlnn

Answer 10

And yes, A is correct. I am telling you why :)

Answer 11

2? I'm assuming i'm only supposed to count the ones in between.

Answer 12

Almost, it's 3. You count the number of units :)

Answer 13

So 3 is our rise in the equation \(\rm slope = \dfrac{rise}{run}\)

\(\rm slope = \dfrac{3}{run}\)

Now to find the run, we see how many units we go RIGHT to meet up with the point (1, 0) from (0, 0) http://prntscr.com/6izm86

Answer 15

1?

Answer 16

Right! So our run is 1. 3/1 = 3 so our slope is 3

Answer 17

If your slope was 1/3 it would look like this http://prntscr.com/6izn34 because it is going up one unit, right three units

Answer 18

OK thanks @sammixboo

Answer 19

If it was -3 it would look something like this http://prntscr.com/6iznbo Because it is going DOWn 3 and going right 1

Answer 20

No problem :3
