Example 4.65 from Elementary Algebra, 4.6 Find the Equation of a Line

Find the Equation of a Line: example 4.65

Find an equation of a line parallel to $y = 2 x - 3$ that contains the point $(−2, 1)$ . Write the equation in slope–intercept form.

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

Does this equation make sense? What is the y-intercept of the line? What is the slope?

Your turn

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

Find an equation of a line parallel to the line $y = 3 x + 1$ that contains the point $(4, 2)$ . Write the equation in slope–intercept form.
