Question

Which of the following are ordered pairs for the equation y = 1/2x + 2?

(0,2) (2,3) (-2,1)


(0,2) (2,-3) (-2,0)


(0,2) (2,-3) (2,0)


(0,2) (-2,-3) (-2,0)

Answer 1

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.

Answer: (0,2)(2,3)(-2,1)
