8. Five mark exercise problems - I

1. The equation of a straight line is \(2(x - y) + 5 = 0\). Find its slope, inclination and intercept on the \(Y\) axis.

 

2. The hill is in the form of a triangle has its foot at \((19,3)\). The inclination of the hill to the ground is \(45^{\circ}\). Find the equation of the hill joining the foot and the top.

 

Answer:

 

The equation of the hill joining the foot and the top is \(x - y - 16=0\)\(x + y - 16=0\)\(x + y + 16=0\)\(x - y + 16=0\).
