Question 187095: I need help with finding the slope because in math class today my teacher went over it and about rise and run, but i mostly forgot!!!!! Please help me!!!! some examples are { Find the slope of the line that passess through each pair of points. A(-10,6), B(-5,8). I think tha i'm sussposed to put it into a fraction... but im not sure?!?!?!?!? If you understand what is Private tutoring??
Thank you soooooooooo much
Liz
{P.S. i'm a 6th grader}

---------------------------
It's sometimes called rise over run, the "rise" being the change in vertical, the y-axis, and "run" the change in horizontal, x-axis, between the 2 points.
--------------------------------------------------
For your example, find the rise by subtracting the y value of one point from the y value of the other.
diff in y = 8-6 = 2
diff in x = -5 - (-10) = +5
The slope is 2/5
------------
That's all it is. It's a fraction for this one, but it can be an integer, and it can be negative. m is usually used for slope.

Remember that your points are expressed as ordered pairs (x,y).

Step 1: Subtract the second y value from the first y value:



Step 2: Subtract the second x value from the first x value:



Step 3: Divide the results of Step 1 by the results of Step 2:




In general, given and the slope of line through and is given by:



Note that it doesn't matter which of the two points you say is the 'first' and which the 'second' because, specifically for your problem:



And in general:
