How do you figure out the slope without drawing the graph? I kinda forgot. I have a chart with data, and I need to know the slope
please help
thank you

help please?!

slope is the change in y divided by the change in x
Pick two data points
(x1,y1) (x2, y2)
slope= (y2y1)/(x2x1) 
yes, that's what i meant. i meant to pick two points, not just one.

ysub2ysub1
= slope
xsub2xsub1
the points are (x,y), obviously. just fill it in.
