standard_description: Prove the slope criteria for parallel and perpendicular lines and use them to solve geometric problems (e.g., find the equation of a line parallel or perpendicular to a given line that passes through a given point).
problem_activity: Identify the slope and
$$y$$
-intercept of the equation
$$12x-8y=24$$
.
Then graph the line that represents the equation.
