The point (2, 1) is on the line given by which equation below? A. y=x+1 B. y = 2x C y = 1/2x D. Y = -2x

C. y = 1/2x

Step-by-step explanation:

We can check to see which of the equations passes through (2,1) by substituting the point's x and y values into the options, then checking to see if the result is a true statement.

Let's try this with option C, . To substitute the x and y values of (2,1) into the equation, substitute 2 for and 1 for . Then, solve:

1 does equal 1, so the result is a true statement. Option C is the answer.
