Assignment #31 Name:________________________________ Plotting Points; Vertical and Horizontal Lines **Use the coordinate planes provided on a separate sheet of paper àο Plot the four points on the coordinate plane. Connect the points to form a rectangle. 1.) Find the PERIMETER: (−4 , 0) (−4 , 6) (5 , 0) ( 5, 6) Perimeter: ___________ 2.) Find the AREA: (0 , 0) (−4 , 0) (0 , 7) ( −4, 7) Area: ___________ àο Plot the three points on a coordinate plane. Connect the points to form a triangle, then find the !

Area: __________ Area: __________ àο Graph and label the three lines on the same coordinate plane. If the lines cross, label the coordinates of the point where the lines meet. 5.) π¦ = 5 , π₯ = 4 , π¦ = −1 6.) π¦ = 3, π¦ = 0 , π₯ = −2 π¦ = −4 , π₯ = 0 , π₯ = 2 7.) àο Graph the four lines on the same coordinate plane. From the rectangle formed by the lines, find: 8.) Perimeter: π¦ = 0, π₯ = 4, π¦ = 6, π₯ = 0 Perimeter: ___________ 9.) Area: π¦ = 6, π₯ = −4 , π¦ = −1 , π₯ = 5 Area: _____________ àο Use the graph below to answer questions 10-­β14: Marks Bank Account Balance: $20 $15 Marks Money $10 $5 Jan Feb. Mar. Apr. May Jun.
