The line l1 l_1\,l1 passes through the point (9,−4)(9, -4)(9,−4) and has gradient 13\displaystyle \frac{1}{3}31.
Find an equation for l1 l_1\,l1 in the form ax+by+c=0ax + by + c = 0ax+by+c=0, where aaa, b b\,b and c c\,c are integers.
The line l2 l_2\,l2 passes through the origin O O\,O and has gradient -2. The lines l1 l_1\,l1 and l2 l_2\,l2 intersect at the point PPP. Calculate the coordinates of PPP.
Given that l1 l_1\,l1 crosses the yyy-axis at the point CCC, calculate the exact area of △OCP\triangle OCP△OCP.
