Graph the original equation. (Click Graphit to remove the instruction box). Then using your knowledge about parallel and perpendicular slopes, graph the point it asks for, and another point that satisfies the parallel or perpendicular equation it is asking for. [br]In "select formula studying" select point- slope which is the y-y1 = m(x-x1). Then enter the slope and the point given. Looking at the graph, or converting point-slope form into slope-intercept form, write the equation in slope-intercept form into "answer here." Nothing on your end will change. (Don't worry too much about the rest of the blanks. As long as you can see point-slope form change into slope-intercept form, you are fine!) After graphing the two lines, click validate to see if you graphed them correctly. [br][br]Repeat this process with a different type of question (if your first question was parallel, click new problem until you get a perpendicular question, or vice versa!)

Given a line in slope-intercept form and a point; find the slope-intercept form of a line through the given point which [br]is parallel/perpendicular to the given line. Plot both of the lines at the right.
