4(a). Find the equation y = ax + b of the line passing through (2,3) and (5,8). (Your answer should be an equation of the form y = ax + b, for some constants a and b.)

(b) Find the equation y = ax^2 + bx + c of the parabola passing through the points (-2, -6), (1,6), and (3,4). (Your answer should be an equation of the form y = ax^2 + bx + c, for some constants a, b, and c.)

Hint: Substituting the x- and y-coordinates of a point into the equation y = ax^2 + bx + c will produce a linear equation in a, b, and c. Do this for the three given points to get the three linear equations. Then solve the system of linear equations.

9. A line passing through the origin is described by the equation y = Mx, where M greater than or equal to 0 is a random slope. Let (theta) be the angle between this line and the horizontal axis, in the right side of the plane. Suppose that theta is uniformly distributed between 0 and 90 degrees (0 and pi/2 radians). What, then, is the pdf of M? What is the expected value of M?
