Question
Given a line containing the points (1,3), (2,4), and (3,5) determine the slope-intercepts form of the equation, give one additional point on this line and graph the function.

Answer
All three of these points are on the same straight line and it only takes two points to find the equation.  
Just take y=mx+b and put the points in, so you have
3 = m(1)+b and 4 = m(2)+b so m=1, b=2
One additional point is (94,96)
You can graph it.  Just pick any two points you were given and draw a straight line through them.
