# Equations of diagonals of the square formed by the lines x = 0, y = 0, x = 1 and y = 1 areA. y = x, y + x = 1B. y = x, x + y = 2C. 2y = x, y + x = D. y = 2x, y + 2x = 1

Given lines are x = 0, y = 0, x = 1 and y = 1 form a square of side 1 unit By the given lines we form a square OABC having corners O (0, 0),

A (1, 0), B (1, 1) and C (0, 1).

Now, we find the equation of diagonal AC

We know that, when two points are given then, equation of line is  y = -1 (x – 1)

y = -x + 1

x + y = 1

Equation of diagonal OB is y = 1 (x)

y = x

Hence, the correct option is (a)
