Consider the contour represented in the following figure. The points marked on the figure are A(3, 1), B(0.5, 1), and O(0, 0). a ) Find the equation representing the line from O to A: y = 1/3x Find the equation representing the line from A to B: y = X Find the equation representing the line from B to O: y = Xb) Use Green's Theorem to find the line integral $ v . dr, where v = 3x yi + yj, and where C is from part (a). avy aVI fe v . dr = SSregion { }dxdy ax ay f v . dr = SSregion { }dady f v . dr =
