,SECTION A
QUESTION 1
In the diagram below, KLM is a triangle with vertices K(2 ; 2), and L ( d ; 4) and M (-10 ; -4). P is the
center of KLM.
The equation of the straight line LM is y−x =6given by
The angle formed by Lm and the x−¿ axis is β .
1.1 Given the equation of straight line LM as y−x =6. Write down the numerical value
of the gradient of LM. (1)
1.2 Determine:
1.2.1 The size of β , the angle of inclination of LM. (2)
1.2.2 The numerical value of d (2)
1.2.3 The coordinates of P. (2)
1.3 1.3.1 Write down the gradient of the straight line parallel to straight line LM. (1)
1.3.2 Next, determine the equation of the straight line parallel to LM and
passing through point K. (2)
