Answer and see the solution →The equation of a curve is y = x^2 − 6x + 8. The straight line y = 2x − 4 is also drawn.
(a)[3 marks]Solve the equation x^2 − 6x + 8 = 2x − 4 algebraically.
(b)[2 marks]Write your solutions as coordinates of the points of intersection between the curve and the line.
(c)[2 marks]On the same axes, sketch the curve and the line, clearly showing the intersection points.
