Slope of the perpendicular line: The symbols introduced in this chapter appear on the inside front covers.

Graphing Exponential Functions How to graph exponential functions by plotting points, the characteristics of exponential functions, how to use transformations to graph an exponential function.

It is a horizontal line. Some students find it useful to label each piece of information that is given to make substitution easier. Since parallel lines have the same slope, what do you think the slope of the parallel line is going to be?

If you said undefined, you are right on. Thank you for considering it! Substituting into Equation 1 yields Note that we get the same result if we subsitute -4 and 2 for x2 and y2 and 3 and 5 for x1 and y1 Lines with various slopes are shown in Figure 7.

When we reach the goal I will remove all advertising from the site. Perpendicular Lines and Their Slopes In other words, perpendicular slopes are negative reciprocals of each other. This one is a little trickier. Since parallel lines have the same slope what do you think the slope of any parallel line to this line is going to be?

Now you need to simplify this expression. This form can be handy if you need to find the slope of a line given the equation. And we are done. You can take the slope-intercept form and change it to general form in the following way. How is this possible if for the point-slope form you must have a point and a slope?

What is the slope of a vertical line? And instead of being a negative, it's going to be a positive. So if we can find the slope ofwe will have the information we need to proceed with the problem.

Slope of the parallel line:Enter the equation you want to plot, set the dependent variable if desired and click on the Graph button.
