THE SLOPE IS FOUND BY (Y2-Y1)/(X2-X1). THUS:
(9-1)/(3+5)=8/8=1 WHICH IS THE SLOPE OF THE LINE PASSING THROUGH THESE 2 POINTS.
thus we have the line equation of: y=x+3
now we need to find the y intercept by substituting one set of point x & y values into the line formula [Y=mX+b] and solve for b which isthe y intercept:
(graph 300x200 pixels, x from -10 to 10, y from -10 to 10, y = x +3).
