just set the lines equal to each otherThe line m with the equation 2x + 3y = 15 meets l at the point C
(B) Determine the coordinates of C
you have and
now solve for and then you can solve for and then you have your point
first, find the corresponding y-coordinate for x = -3 on the line mTHe point P lies on m and has x co-ordinate of -3
(c) Show by caclulation PA = PB
Thanks in advanced
you can use the distance formula to find the length PA and the length PB and show they are equal to each other.
