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: ____________________.
