A (- 2, 4), C (4, 10) and D (- 2, 10) are the vertices of a square ABCD. Use the graphical method to find the co-ordinates of the fourth vertex B. Also, find :

(i) the co-ordinates of the mid-point of BC;

(ii) the co-ordinates of the mid-point of CD and

(iii) the co-ordinates of the point of intersection of the diagonals of the square ABCD.

Line y + 7 = 0 is :

1. parallel to x-axis

2. parallel to y-axis

3. not parallel to x-axis

4. not parallel to y-axis

6x - 5y = 7 is the equation of a line. If x = 2 then the value of y will be :

1. 1

2. -1

3. 5

4. -5

For equation $\dfrac{x}{3}-\dfrac{y}{2}$ = 1, the value of y for x = 9 is :

1. -4

2. 6

3. 4

4. -6
