The slope of the line, $$y=a x+b$$ is 2 , which means $$a=2$$, so the equation of the line is $$y=2 x+b$$ (The equation of a line having slope ' $$m$$ ' and $$y$$-intercept ' $$c$$ ' is $$y=m x+c$$ )

To find the value of the $$y$$-intercept of the line is same as finding the value of $$b$$.
Next the x -intercept of the line is 5 means $$(5,0)$$ satisfies the equation of line, so we get $$0=2 \times 5+b \Rightarrow b=-10=y-$$ intercept (Note: $$-x-$$ intercept of a line is the value of $$x$$ when $$y$$ is 0 ).

Hence column A quantity equals column B quantity, so the answer is (C).
