Hey,
This is my first post on the board, so I'd just give some basics about myself, I'm 13 and in Algebra 1, a 9th grade course in 8th Grade. I don't understand how to find the slope when it is graphed on a coordinate plane. I've tried the problems, and looked in the text book itself, and still cannot figure it out. The first problem looks similar to the following:

Click to expand...

So you know the definition of slope correct?

Slope = (increase in y-value)/(increase in x value) = (rise)/(run)

In your graph - you can see that the value of y goes from 0 to 3 (increases by 3 ) as x goes from 0 to 3 (increases by 3)

so slope = ((increase in y-value)/(increase in x value) = 3/3 = 1

Please let us know if you need further explanation....
