Answer 2

Hi, Jacqui!

How comfortable are you with the concept of slope? rise/run?

You are given an illustration of a line on the xy plane . To calculate the slope, you may choose any two points on that line. Then, ask yourself: how much does x change as you go from one point to the other one? How much does y change?
change in y
The slope would then be m = -------------
change in x.

Answer 3

Not quite comfortable. But I'll try it

Answer 4

Your graph shows the specific points (-3,-4) and (4, 1).
How much does x change as we go from the first point to the second? Hint: 4-(-3)=?

Answer 5

Next: how much does y change as we go from (-3,-4) to (4,1)?

Answer 6

Umm, I don't know ._. I feel ashamed because I am dumb to this slope stuff >.<

Answer 7

Your graph shows the specific points (-3,-4) and (4, 1).
How much does x change as we go from the first point to the second? Hint: 4-(-3)=?
Note that 4-(-3)= 4+3 = 7. This is the change in x.

Do the same thing for the change in y. how much does y change as we go from (-3,-4) to (4,1)? What is 1-(-4)?

Answer 8

5?

Answer 9

\[\frac{ 7 }{ 5 }\]

Answer 10

How very embarrassing! My mistake. The change in x is 7 and the change in y is 5, so the slope is

m=5/7. Sorry for having caused this confusion!

Would you like to discuss this problem further, or to move on to another?

Answer 11

Ohh it's 5/7

I'd like to move on, I get it c:

Answer 12

Great. Just post your next question in the usual way.

Answer 13

Alright, Thanks for helping c:
