Question 783817

Ok so I have a graph that has one point on it the point is (2,1) my chooses are y=1/4x
y=10x
y=5x
y=1/2x 
I have no clue as to what i'm looking for please help me 


Substitute the point (2, 1) in each choice, with 2 for x, and 1 for y.


The choice {{{highlight_green(y = (1/2)x)}}} becomes a TRUE equation when the values for the coordinate point (2, 1) are substituted.
