Coordinates

  1. 1. COORDINATES
  2. 2. TO PLOT POINTS, GIVEN THE COORDINATES ANDTHE SCALES Plot the points E (3,4), F (6, - 4) and H (-3,12) given the scales for the x-axis and y-axis are 1:3 and 1:4. 4
  3. 3. TO POSE AND SOLVE PROBLEMS INVOLVINGCOORDINATES Name the shape formed by the points D (0,3), E(2,0), F(0,-3) and G(-2,0). Plot the points.
  4. 4. DISTANCE BETWEEN TWO POINTS IN ACARTESIAN PLANEa) Points with common y-coordinates - Find the distance between the points A(4,2) and B(9,2) AB = 9-4 = 5units- Plot the points A and B in a Cartesian plane andnote that AB is parallel to the x-axis
  5. 5. b) Points with common x-coordinates - Find the distance between points M(-7,3) and N(-7, 7) MN = 7-3 = 5 units- Plot the points M and N in a Cartesian plane and note thatMN is parallel to the y-axis
  6. 6. EXAMPLEa) Q(2,3) and R(4,3) = 4-2 = 2 unitsb) S(-4,-7) and T(-4,2) = 2-(-7) = 9 unitsc) D (-4,9) and E(-12,9) = -4-(-12) = 8 units
  7. 7. EXERCISE P Q Distance of PQ 8-4a) (4,5) (8,5) = 4 unitsb) (-2,3) (4,3)c) (5,-5) (-6,-5)d) (3,-7) (7,-7)e) (-5, -4) (-5,-8)
  8. 8.  The end
