when a graph is in slope-intercept form (y =mx +b) then the last number is the y-intercept. in the equation m=the slope and b=the y-intercept. then you plug it into a point (x, y)
when a graph in slope intercept from ( y= mx+b) then the last number is the y - intercept in the equation m= the slope and b = the y - intercept then you you plug it into a point ( x, y)
