What is the Capital Asset Pricing Model, CAPM, equation? and what does it tell you?

The CAPM equation is The expected return of an investment E(r) = the Risk-free rate + Beta, the systematic risk of the investment, * the market risk premium, the return of the market over the risk-free rate. In-short, E(r) = Rf + B(Rm-Rf). This tells us what we can expect to return given our level of systematic risk, risk that can not be diversified.

What is concept of the IRR? Why would we use the MIRR?

The IRR is the rate of return that brings our projects NPV, the present value of future cash flows, to 0. It is useful in determining if an investment exceeds your companies minimum required return. We use MIRR when there are multiple inflows and outflows but in different periods.

Given the two sets of points find the slope and the y-intercept of the set. Set one (4,8) Set two (6,5)

To solve this problem we need to use the slope intercept equation, y =mx+b.The first step we need to do is to find the slope of the two sets, the letter m. The equation to find the slope is (y2-y1) / (x2-x1). Using this equation we will get (5-8) / (6-4) which gives us -1.5. Now we can plug in the slope of -1.5 to the slope intercept equation to find the y- intercept, the letter b. We can use any set, but for this example we will use the first set (4,8). Using this set, we come up with 8 = -1.5(4) + B. In the end we find the answer to B is 14. Thus the answer to this question is slope = -1.5 and the y-intercept is 14
