A.Maths Straight line question!!
A line makes intercept h on the x-axis and intercept k on the y-axis. The line passes through (1,2). Express h in term of k.
Answer; h= k/(k-2)
If i don't want to use intercept form, wt can i do ??

By intercept form of straight line,
the equation of straight line is
Put x=1, y=2

===ALTERNATE SOLUTION===Let the equation of straight line bey=mx k (since y-intercept=k)Put x=1, y=22=m k --(1) Put x=h, y=00=mh k -(2)Eliminate m from (1) and (2),0=(2-k)h kh=k/(k-2) (ANS)
