Help, can't figure this one out.
Draw a line perpendicular to the line that contains the points
(1, 6) and (4, 4) and passes through the point (−2, 6).
OK..... can you tell me what the equation for the line is?
See if you can figure THAT out and repost on this thread for more help.....
What you need to do is realise that the line that goes through (1,6) and (4,4) has a gradient of -2/3 (using rise/run). Any line perpendicular to this will have a negative reciprocal gradient, as perpendicular lines' gradient multiply together to give -1. The gradient of the line will thus be 3/2. All you have to do is find the equation of the line that has a gradient of 3/2 and also passes through (-2,6), and sketch it.
