Parametrization of a curve

Thanks, works perfectly for #6 where the function is simple [2y,2x] and the slope was simply 3t. I tried the exact same procedure on #7. however the function is now [8(4x+9),18(4x+9y)] and the slope is -1/6 from points (-9,4) to (3,2). I wonder if the variable bounds are [-9,3]? The book gives a solution of… (read more)
