  1. Bell Work Plot and describe the location of each point A(5, -2) B(2,3) C(0, 3) D(1,0) E(0,0) F(-3, -4) G(-4,3)

  2. The Coordinate Plane Day 2 We will make something like this on Friday connecting points on a coordinate plane!

  3. Give the coordinates of the point. ANSWER ANSWER ANSWER ANSWER (3, 0) (–2, –1) (1, –4) (–1, 1) Review 1. G 2. H 3. J 4. K

  4. ANSWER Point S(- 2, 1) is in QuadrantII. The correct answer is D. Review SOLUTION Plot points P, Q, R, and S on a coordinateplane. Point P is located inQuadrantIV.Point Q is located inQuadrant III.Point R lies on the y-axis.Point S is located in QuadrantII.

  5. Find the length, width, area and perimeter of rectangle ABCD. SOLUTION The length of the rectangle is the horizontal distance between A and B. Length = 4 + 4 = 8 units The width of the rectangle is the vertical distance between A and D. Wide = 2 + 2 = 4 units

  6. 32square units Area lw = = = 8(4) Area and Perimeter The area of the rectangle is found by multiplying the length and width. The perimeter of the rectangle is found by adding all sides together or adding two times the length plus two times the width. Perimeter = l + l + w + w = 8 + 8 + 4 + 4 = 24 units or 2l + 2w = 2(8) + 2(4) = 16 + 8 =24 units

  7. You try: Find the perimeter and area. Points A, B, C, and D form a figure. What is the figure? A B a rectangle To find the length (l), find the horizontal distance from A to B 7 units To find the width (w), find the vertical distance from B to C. 9 units D C units 32 Perimeter= 2 L + 2 W = 2 (7) + 2 (9) 63 units squared Area = L x W length x width 7 x 9 =

  8. Find the length, width, area and perimeter of rectangle ABCD formed by the points A(1, -4),B(4, -4),C( 4, -2), and D(1, -2). You Try: SOLUTION- Graph it

  9. 6square units Area lw = = = 3(2) Solution! The length of the rectangle is the horizontal distance between A and B. Length = 3units The width of the rectangle is the vertical distance between A and D. Wide = 2 units The area of the rectangle is found by multiplying the length and width. The perimeter of the rectangle is found by adding all sides together or adding two times the length plus two times the width. Perimeter = l + l + w + w = 3 + 3 + 2 + 2 = 10 units or 2l + 2w = 2(3) + 2(2) = 6 + 4 = 10 units
