The line AB has equation 5x + 3y + 3 = 0 . (a) The line AB is parallel to the line with equation y = mx + 7 . Find the value of m. [2 marks] (b) The line AB intersects the line with equation 3x -2y + 17 = 0 at the point B. Find the coordinates of B.

Rearrange line into standard form. y=5/3*x +1 For parallel lines the gradient is the same therefore m = 5/3 Point of intersection is where two lines equal eachother multiply out to elminate x term 15x + 9y +...

Rearrange the following to make 'W' the subject: aw + 3 = 4(bw + 5)

aw + 3 = 4(bw + 5) Let's get rid of those brackets... aw + 3 = 4bw + 20 Now we rearrange... aw - 4bw = 17 Factorise... w(a - 4b) = 17 Final rearrange... w = 17 / (a - 4b) Done.
