Math calculus, please show all steps

Consider the parametric equations x = 1 + - and y =t-3. a. Create a table to sketch the curve represented by the parametric equations. Be sure to indicate the orientation of the curve. b. Find the corresponding rectangular equation, writing y as a function of x. c. Determine the (x, y) coordinates and the value of the parameter at the point(s) where the slope of the tangent line to the curve is 4 Name: d. What is the concavity of the graph at the point where t = -/? Be sure to use calculus to answer this
