Given an equation of a line, find equations for lines parallel or perpendicular to it going through specified points. Find the appropriate equations and points from the table below. Simplify your equations into slope-intercept form.
Write the equation of a line parallel to the given line and passing through the given point. Write the equation of a line perpendicular to the given line and passing through the given point.
Assigned problem below**
y = ½ x + 3; (-2, 1)
Discuss the steps necessary to carry out each activity. Describe briefly what each line looks like in relation to the original given line.
Answer these two questions briefly in your own words: 
What does it mean for one line to be parallel to another?
What does it mean for one line to be perpendicular to another?
