Algebra 1 Name ___________________________ Section 3-9 Date _____________ Writing Equations of a Line Given a Point and the Slope What is the general form of a linear equation in slope-intercept form? _____________________ m is the ____________________ and b is the _________________________ Example 1: Suppose you know that a line has a slope of -5 and passes through the point (2, -4). What do you need to find in order to write the equation of the line? Label all of the numbers with the corresponding letter. Plug each number into the equation and solve. The equation is: ____________________. Example 2: Write the equation of a line that passes through the point (6, 17) and has a slope of 3 . 2 Example 3: Write the equation of a line that passes through the point (-4, 0) and has a slope of 5.
