Consider the following parametric equations. a. Eliminate the parameter to obtain an equation in x and y b. Describe the curve and indicate the positive orientation. X =1-5, y=13-7, -35rs3a. Eliminate the parameter to obtain an equation in x and y (Type an equation.) b. Describe the curve and indicate the positive orientation. (Type ordered pairs. Simplify your answers.) O A. A quadratic curve falls and then rises to the left as r increases, starting at and ending at B. A cubic curve falls to the left as I increases, starting at and ending at O C. A cubic curve rises to the right as r increases, starting at and ending at O D. A quadratic curve falls and then rises to the right as r increases, starting at and ending at
