Answer

Math Assignment

  1. Question One

Distance between points K and C;

Displacement = √(x­­1-x­)2 + (y1-y2)2

D = √(9-2)2 + (-9+4)2

    = √74

    =8.6

 

  1. Question Two

Midpoint M between C and D;

 

  1. Question Three

Equation of a circle;

(x-x1)2+ (y-y1)2 = r2

(x – 7)2 + (y + 2)2 = 81

x2 – 14x + 49 + y2 + 4y + 4 = 81

x2 + y2 – 14x + 4y – 28 = 0

 

  1. Question Four

Graph of line

  1. Question Five

x and y-intercepts of 6x – 3y = 12

x-intercept (y = 0); 6x = 12

                                  x = 2

y-intercept (x = 0); -3y = 12

                                  y = -4

x-intercept = (2,0)

y-intercept = (0,-4)

 

  1. Question Six

Slope of the line passing through (2,5) and (8,-4)

Slope =

Slope

 

  1. Question Seven

Equations for the horizontal and vertical lines passing through (-7,-4);

Horizontal; y = -4

Vertical; x = -7

 

  1. Question Eight

Slope and the y-intercept of the line 6x – 3y = -9

Slope = 2

y-intercept = 3

 

  1. Question Nine

Radius and center of a circle x2 + y2 + 4x – 2y – 11 = 0;

x2 + 4x + (4) + y2 – 2y + (1) = 11 + (5)

(x + 2)2 + (y – 1) 2 = 42

Centre = (-2,1)

Radius = 4 units
