Here are some questions I sturggle with.
1.The line y=x+2 meets the curve x^2+4y^2-2x=35 at the point a and b find co ordinates of a and b.
What I did was input one equation into the other : x^2+4(x+2)(x+2)-2x=35 which equals 5x^2+14x-19 and the solutions to this is x=19/5 and x=1
the problem is that a and b do not pass through the x or y-axis.
2 (4 part question managed to do the first 2 parts)
(a) Find equation of line joining A(7,4) and B(2,0) gve answer in ax+by+c=0 format so 4x-5y-8=0
(b)Find length of AB in surd form
4-0=4 7-2=5
square root of 4^2+5^2 which is the root of 41.
(c)The point C has coordinate (2,t) where t>0 and AC=AB
find value of t
(d)Find area of triangle ABC
I cannot do c and b.
