Example 13 from Algebra and Trigonometry, 2.2 Linear Equations in One Variable

Finding the Equation of a Line Passing Through the Given Points

Find the equation of the line passing through the given points: $(1, −3)$ and $(1, 4) .$

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
The x-coordinate of both points is 1. Therefore, we have a vertical line, $x = 1.$

Your turn

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

Find the equation of the line passing through $(−5, 2)$ and $(2, 2) .$
