displaying data from a simple experiment Materials: Meter stick‚ tape‚ and a ball is needed to perform this experiment. Theory: The graph of function is the collection of all ordered pairs graphing on a cartesian plane is sometimes referred to as a curve sketching. Experimental Procedures: Position a meter stick vertically on a flat surface‚ such as a wall or the of a lab bench. be sure the metric scale of the meter stick is on the outside and secure the meter stick to the wall or lab bench with

The purchase of long-lived assets are daily‚ quarterly and yearly occurrences for many corporations. The cost allocation of the asset is shown through the method of depreciation a company uses. The method a company chooses to incorporate should be one that most effectively matches expenses with the revenues produced. The method that most select is that of straight-line depreciation

STRAIGHT LINE MODEL In many investigations‚ two or more variables are observed for each experimental unit in order to determine: 1. Whether the variables are related. 2. How strong the relationships appear to be. 3. Whether one variable of primary interest can be predicted from observations on the others. Regression analysis concerns the study of relationships between quantitative variables with the object of identifying‚ estimating‚ and validating the relationship. The estimated relationship

Straight Line Equations and Inequalities A: Linear Equations - Straight lines Please remember that when you are drawing graphs you should always label your axes and that y is always shown on the vertical axis. A linear equation between two variables x and y can be represented by y = a + bx where “a” and “b” are any two constants. For example‚ suppose we wish to plot the straight line If x = -2‚ say‚ then y = 3 + 2(-2) = 3 - 4 = -1 If x= -2 -1 -1 1 0 3 1 5 2 7 As you can see‚ we have plotted the

EXERCISE 2STRAIGHT LINES Question 1: Write the equations for the x and y-axes. Answer : The y-coordinate of every point on the x-axis is 0. Therefore‚ the equation of the x-axis is y = 0. The x-coordinate of every point on the y-axis is 0. Therefore‚ the equation of the y-axis is x = 0. Question 2: Find the equation of the line which passes through the point (–4‚ 3) with slope . Answer : We know that the equation of the line passing through point ‚ whose slope is m‚ is . Thus‚ the equation
