What do the variables "m" and "b" represent?

The slope intercept formula is, #y=mx+b#

where #m# is the slope
where #b# is the #y#-intercept

The slope is the change in y over the change in x. This is commonly known as the #(rise)/(run)#. This is also shown as the #(Deltay)/(Deltax)#. If you have any 2 points on the line than you can also use the formula #(y_2-y_1)/(x_2-x_1)#.

The y-intercept is where the line touches or intersects the #y#-axis. If the #x# coordinate is zero you can find out what the y-intercept is.
