no, it should be

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

so,

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.
