Answer 2

Y = X passes to quadrants I and III

Step-by-step explanation:

Given equation states y = x

Now, let's substitute 2 negative and 2 positive values for x.

When x = 2, y will be 2. So the co-ordinate will be (2, 2)

When x = - 2, y will be -2. So the co-ordinate will be (-2, -2)

When x = 5, y will be 5. So the co-ordinate will be (5, 5)

When x = -5, y will be -5. So the co-ordinate will be (-5, -5)

If we plot a graph and join the co-ordinates (2, 2), (-2, -2), (5, 5) and (-5, -5), it will be a diagonal straight line which passes through the quadrant I and quadrant III

Please refer to the picture to know where the quadrants lie.
