Solve the system of equations y = 3x - 5 and y = 1 3 x + 3 using a graphical method.

Plot these 2 separate functions on the same set of coordinate axes.

first one:  y = 3x - 5.  Slope is 3 and y-intercept is -5.  Start at (0,-5), move your pencil from that dot 1 unit to the right and then 3 units up.  Plot another dot there.  Draw a str. line thru these 2 dots.

Do the same thing for the other:  y = 13x + 3.  Slope is 13, y-intercept is 3.

From your graph of these 2 lines, you should be able to determine visually the coordinates of the pt. of intersection.
