Unfortunately for this problem you will have to go through each set of points individually until you get 3 equal answers in a row. To do this simply put the value of x and y given as a point on the graph and plug them into the equation like so: 2 = .5(0) + 2
This turns out to be 2 = 2 which means that point falls on a line created by the equation.
Then repeat until one of these has all three like this.
