Question

which is a solution of the equation 2x-y=5 A 7 B (3, -1) C (2, -1) D (1,2)

Answer 1

Have you done this kind of problem before?

You're given a linear equation, 2x-y=5, along with four points written as coordinate pairs, e. g., (1,2).

All you have to do is to substitute the x and y values from each point into the equation and determine whether the equation is true or not. If it's true, that point (ordered pair of numbers) is a solution. Otherwise it's not. Please try this.

Answer 2

I agree. But to make it easier for you the answer is C. (2,-1). Just substitute 2 & -1 for x & y.
