Question

The equation of a line through the intersection of lines x = 0 and y = 0 and through the point (2, 2), is

• A. y = x – 1
• B. y = –x
• C. y = x
• D. y = –x + 2

Answer 1

The correct option is C y = x

Obviously the point of intersection is (0, 0). Thus the equation of line passing through the points (0, 0) and (2, 2) is (y - 0) = (2 - 0)/(2 - 0) (x - 0) which is y = x.
