hi guys:
Ok so this is part iii. to a question but i'll include all thats needed.
The two tangents intersect at the point D. The the y-coordinate of D.
The tangents are y=8x-4 and y=-2x-(1/4)
Im not particularly sure what to do once i've put them equal to each other:
8x-4 = -2x-(1/4)
If I put them all on one side I get 10x - 3.75 = 0
The answer is y=-1
