do you know how to calculate the slope of a line given 2 points on the line?

anonymous · Answer

no i dont understand this type of math at all

triciaal · Answer

the slope of the line is the change in y / corresponding change in x 
sometimes this is referred to as the rise over the run
its just the ratio of how much the y value changes as you change the x value |dw:1411342716015:dw|
