so y=y
m=slope or rise/run means rise divided by run or (how far up)/(how far to the right)
x=x
b=where the line passes throught the y line, aka the y intercept so
if you had the equaiton y=2x+3
the slope=2/1 or for every 2 units you go up, you go 1 to the right
3, the line passes thorought the y line at +3
