Question

Which is the equation of the graphed line written in standard form?

A. y=x

B. x-1/2y=0

C. x-y=0

D. y=1/2x

Answer 1

The standard for of this equation is x – y = 0

Firstly, options A and D are not in standard form, so they are not options.

To decided between B and C, we choose a point on the line and see if it works. For example, we'll use (2, 2).

x – y = 0

2 - 2 = 0

0 = 0

This is true for option C. Therefore, it is correct.

hope this helps
