Question

the line 1 passes through the points (9, -4) and has gradient 1/3. find an equation for line 1 in the form ax+by+c=0, where a,b and c are integers

-the line l2 passes through the origin O and has gradient -2. the lines l1 and l2 intersect at the point P. calculate the coordinates of P.

Answer 1

y-(-4)=(1/3)(x-9)
y+4=(1/3)x-3
(1/3)x-y-7=0
or
x-3y-21=0

Answer 2

Thanks a lot :)

Answer 3

any other doubts.....
