Example 11.42 from Prealgebra, 11.4 Understand Slope of a Line

Understand Slope of a Line: example 11.42

Graph the line passing through the point $(−1, −3)$ whose slope is $m = 4 .$

Work it out on paper first. Then open the solution one step at a time, and stop as soon as you can finish on your own.

Solution
Plot the given point.

Identify the rise and the run. $m = 4$

Write 4 as a fraction. $\frac{rise}{run} = \frac{4}{1}$

$rise = 4 run = 1$

Count the rise and run.

Mark the second point. Connect the two points with a line.

Your turn

The book's Try It right after this example: same idea, new numbers. Only the answer is given.

Graph the line with the given intercept and slope: $(−2, 1), m = 3 .$

How did it go?
