parametric question:
Find the PQ for y if x = e^t for the line passing through the points (2,1) and (-2,3).
I know basic parametrics, but how do I solve a question like this??

dumbcow · Answer

x = e^t    ----> t = ln(x)   

the point (-2,3) cant exist since "x" is negative ??

loser66 · Answer

the line passes through the points (2,1) and (-2,3) has equation $y= 2-\dfrac{1}{2}x$, replace $x=e^t$ you have the parametric equation for y is $y= 2-\dfrac{e^t}{2}$
