Chapter 4
Graphs and Equations of Lines
Lines are graphs of linear expressions. When graphing lines or writing their equations, you have the slope intercept form,
The Problems You’ll Work On
In this chapter, you’ll work with the graphs and equations of lines in the following ways:
Graphing a line given a point and a slope
Graphing lines given two points
Graphing a line parallel or perpendicular to a particular line
Writing the equation of a line given a point and a slope
Writing the equation of a line given two points
Writing the equations of lines either parallel or perpendicular to a given line
What to Watch Out For
Don’t let common mistakes like those that follow trip you up when working with the graphs and equations of lines:
Drawing a line with a positive slope rather than a negative slope
Not using the slope formula correctly when inserting the coordinates of points
Forgetting to change the sign when determining the slope of a line perpendicular to a given line
Distributing incorrectly when simplifying the point-slope form
Sketching Lines Using a Point and Slope
191–210 Sketch a graph of the line described.
