Q:

The speed of a snowboarder from uphill to downhill can be modeled using the equation y=x^2+1 where x is in minutes. The snowboarder's speed at time 0 is 1 and is 2 at time 1. The snowboarder claims that this proves his speed increases linearly. Is he right? A. Yes, because two points are needed to define a lineB. No, because the equation is not linearC. No, because the two points have positive values onlyD. No, because it does not cross the x-axis

Accepted Solution

A:
answer is B.
It's not true since the equation is not a linear equation.
hope this helps
