# Graph the parametric equation x(t)=3t and y(t)=2-2t on [0,1] ?

##
Write one Cartesian equation (x and y only) that models this graph. Identify the initial and terminal points.

This is for my precalc BC class and I never learned this last year so I appreciate all the help I could get :)

De-parameterize:

For

#{(x(0) = 3 * 0 = 0 ),(x(1)= 3*1 = 3):} qquad {(y(0) = 2 - 2 * 0 = 2 ),(y(1)= 2 - 2*1 = 0):}#

graph{y = - 2/3 x + 2 [-1, 4, -1, 3]}
