be aware that the formula to solve any linear equation is y=mx+b. with the said‚ we can say that we have our y- intercept which is 330. (The ordered pair 0‚330 demonstrates that the y coordinate is 330). Since we have our y- intercept‚ we will now discover what our slope is. The formula to determine any slope of a line is m=y1- y2 x1-x2 M= 330-0 0-100 After performing division and simplifying‚ we have found that the slope of our line is -3. a) Write an inequality to describe this

-2.2 In the simple linear regression model y=β0+β1x + u‚ suppose that E(u) ≠ 0. Letting α0=e(u)‚ show that the model can always be rewritten with the same slope‚ but new intercept and error‚ where the new error has a zero expected value. Answers In the equation y = β0 + β1x + u‚ add and subtract α0 from the right hand side to get y = (α0 + β0) + β1x + (u − α0). Call the new error e = u − α0‚ so that E(e) = 0. The new intercept is α0 + β0‚ but the slope is still β1. ≠ 2 Solutions‚ Chapter

how many rubber bands I need .What I did first was graph the table on the paper so that I could make a slope triangle to find out my growth and y-intercept to make an equation to see how many rubber bands I need. First I graphed the table onto my paper because I needed to know my starting point and line of best fit. Then I did a slope triangle because I needed to figure my growth which so the slope triangle was 51/11 and I divided it and got 4.6 to

concrete. To get the average ball-drop height‚ we dropped the ball three times from each height‚ found the mean. Our Y value represents the average bounce heights in centimeters and X represents the drop height in centimeters. We created a scatter plot to show our data (below). The line of best fit went through the points (80‚48.3) and (90‚54.3). To find the slope of the line we used the slope formula: M=(Y2 -- Y1)/(X2 -- X1). If (80‚48.3) is X1 and Y1 then (90‚54.3) is X2 and Y2. After this you take X2

the risk premia in relation to the change in exchange had been introduced by McCallum (1994). McCallum also suggested that the tradeoff between interest-rate and exchange rate stability produced an additional bias in the probability limit of the slope coefficient β in the UIP regression. Culver & Papell (1999) demonstrated statistically‚ using KPSS tests‚ that the combination of rejecting the stationary null hypothesis for nominal‚ but not for real‚ exchange rates constitutes evidence of long-run
