# Linear functions write an equation for a parallel or perpendicular line

To avoid either of these messages and get meaningful resultsit is best to have test data points that are widely separated in at least two of the three parameters Voltage, Current, and RPM. The Catalog Data Input window is designed to make sense of this information. General Equation of a Line: The properties of the line such as slope and x and y intercepts are also explored. The investigation is carried out by changing the coefficients a, b, and c and analyzing their effects on the properties of the graph.

The properties of the graph such as slope and x and y intercepts are also explored. Interactive Tutorial Using Java Applet Click on the button above "click here to start" and maximize the window obtained. Example Find the x and y intercepts of the graph of the equations given below. The x intercept is at 10. The y intercept is at 0 The x intercept is at 00.

The y intercept is at 00. This will define equation in the example above, part a. Locate the x and y intercepts and compare with the solution above. This will define equation in the example above, part b. Does the position of the x intercept change? Does the position of the y intercept change?

Set a, b and c to some values. Drag the red markers so that they are on the line, read their coordinates and find the slope of the line.

Two parallel lines won't ever intersect. 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.

Perpendicular lines. When we draw y = 3 x and draw a line perpendicular to it passing through the origin then it is clear that y = − ax where a is a small positive number.

We will show that the equation is y = − x.. We are now going to show the surprising result that ‘if two lines are perpendicular then the product of their gradients is −1’ (or if one is vertical and the other.
