A review of the main results concerning lines and slopes and then examples with detailed solutions are presented. If a line passes through two distinct points P1 x1y1 and P2 x2, y2its slope is given by: This is another interactive tutorial on the slope of a line. General Equation of a Straight line:
The major new features are highlighted along with the version number and date in which the feature was implemented. Access the on-line help Press F1 for details on these and other features. A Reset option has been added. This option resets the random number generator seed so that the return values of the Random and RandG functions will change when they are next used.
Also, any equations that are input in Diagram input variables are reset to 1'.
If the parameter is positive, it is used as a seed so the same random number is always chosen. If the parameter is negative, the a random number is chosen and it remains constant for the duration of the time that the file is open. However, a new random number is chosen when EES is restarted or when a file is opened.
This capability makes it possible to use EES to generate 'quiz-type' problems in which the specified inputs change each time the file is opened.
All Palette items can be moved,resized, and converted to animation objects in the Professional version Diagram window.
Right-clicking on an arrow in the Plot or Diagram windows when the tool bar is visible brings up a popup menu with an option to place the arrow at the opposite end of the line. Cell Macro command will accept text within single quotes or an EES numerical or string variable.
A specific plot may be indicated with a numerical value indicating the position of the plot tab or using a string constant or string variable that provides the name of the plot window seen on the tab.
If an plot window designation is not provided then all of the plot windows in the file will be updated. However, the width of the dropdown control may be manually specified.
To do this, right-click on the dropdown control while in development mode to bring up the diagram text properties dialog. Click the Edit button to the right of the Use string list check box to display Enter Strings dialog.
Uncheck the Set Width automatically button and add the desired width in pixels in the Width edit box. Right-clicking on the variable a second time will find the next occurence of the variable.
Also, the color and style of directives appearing in the Equations window can be controlled in the General Display tab of the Preferences dialog. The Professional version will allow the guess, lower and upper value to be provided with an equation involving EES variables.
Data62, Version Thermodynamic and transport property data for RA have been implemented.. Version A 'Calculate' button can be placed on the Diagram window and it can be configured to do a variety of different tasks. A Reset option has been added.
This option resets the random number generator seed so that the return values of the Random and RandG functions will. We'll write the equation of the line that passes through a given point and it makes an angle with the axis of X. (y - y1) = m (x - x1) We know that m = tan a, where a is the angle made by the line.
Write the equation for a line that is a parallel or perpendicular to a line given in slope-intercept form and goes through a specific point. The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.
If you know two points that a line passes through, this page will show you how to find the equation of the line. To establish a rule for the equation of a straight line, consider the previous example. An increase in distance by 1 km results in an increase in cost of $3.
