The equation of the line L1 is y=4x–8. The equation of the line L2 is 3y–12x+4=0. Show that L1 and L2 are parallel.

Parallel lines have the same gradient. The gradient of L1 is 4. For the gradient of L2: 3y=12x-4y=4x-4/3The gradient of L2 is also 4. Thus these lines are parallel. Explanation 1.Rearrange the equation to ma...

Solve the simultaneous equations: x^2 + y^2 = 9 and x + y = 2

Firstly we need to realise that equation 1 (x^2 + y^2 = 9) does not factorise. So once realising this, we must rearrange equation 2 (x + y = 2) so that y = 2 - x. Now we substitute (y = 2 - x) into equation ...
