The graph of the linear equation y = x
Question:

The graph of the linear equation y = x passes through the point

(a) (3/2, -3/2)           

(b) (0,3/2)              

(c) (1,1)                  

(d) (-½,½)

Solution:

(c) The linear equation y = x has same value of x and y-coordinates are same. Therefore, the point (1,1) must lie on the line y = x.
