1.Find the equation of the line joining A(-1, 9) to B(6, 12).(adsbygoogle = window.adsbygoogle || []).push({});

Another line passes through C(7, -5) and meets AB at right angles at D.

Find the equation of CD and calculate the coordinates of D.

Given That the coordinates of M are (K, -2K) and that the distance of AM is [tex]\sqrt{178}units[/tex], calculate the value of K.

How do i calculate the value of K?

2. Q is the reflection of the point(2,9) in the straight line y = 2x. Calculate the coordinates of Q.
