Question

The equation of a line passing 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 $y=x$

The point of intersection of x = 0 and y = 0 is (0, 0).

Thus, the equation of line passing through the points (0, 0) and (2, 2) is

$(y-0)=\frac{(2-0)}{(2-0)}(x-0)$

$\Rightarrow y=x$
