How far from the edge of the wall should she mark the location to nail the picture so that the right side of the picture is 37.5 inches from the wall s left side? 3. Point P is located on the segment between point point (1,4) and point D (7,13). The distance from to P is twice the distance from P to D. What are the coordinates of point P? 4. Parallel lines have slopes. 5. Perpendicular lines have slopes. 6. Determine whether the lines are parallel, perpendicular or neither. a. 2x + 3y = 4 b. y = -4x + 1 c. 2y = x 1 3x - 2y = 3 4x + y = 8 y = -2 x Maggie and Mike want to go to the music store near Maggie s house after school. They can walk 3.5 miles per hour and ride their bikes 10 miles per hour. a. reate a table to show how far Maggie and Mike can travel walking and riding their bikes. b. reate a graph to show how far Maggie and Mike can travel based on the chart above. c. What does the slope represent in the graph? d. Maggie s mom said that they can only go if they can make it to the music store and back in less than two hours. If they want to spend at least 30 minutes in the music store and it is four miles away, can they make it?
