Question

Eliminate the parameter from the given parametric equations to find an equation that relates x and y directly.
1) x=6t-6 , y=2t-5

Answer 1

\[\Large\rm y=2t-5\]Multiply each side by 3,\[\Large\rm 3y=6t-15\]Separate the -15 into -6 and -9,\[\Large\rm 3y=\color{royalblue}{(6t-6)}-9\]\[\Large\rm 3y=\color{royalblue}{(x)}-9\]Understand the steps?
