You may find it simpler to rotate the curve and the line a quarter turn anti-clockwise around the origin. This gives y = x^2/4 and y = 1/2x + 2 They intersect at x = -2 and 4. Find the definite integral over the interval (-2, 4) of 1/2x + 2 - x^2/4. This gives 9 units

Since the two tangents are mutually perpendicular and intersect on the y-axis they have gradients 1 and -1 The gradient function is y = 6x Hence x = 1/6, -1/6 So y = 1/12 both times So the coordinate of the intercept can be calculated using the equation of the tangents: Equate...
