Question

The curve described parametrically by $x=t^2+2t+2,y=t^2+2t+2$ represent

• A. straight line
• B. pair of straight
• C. circle
• D. parabola

Answer 1

The correct option is A straight line

Given, $x=t^2+2t+2,y=t^2+2t+2$.

That is $y=x$ for all $t$.

So $y=x$ represents a line passing through the origin.
