Two lines are parallel when they have the same gradient.
When the equation is written in the form: y = mx + c, m is the gradient.
We need to arrange our equations in the form y = mx + c as this...

Simplify: 6y² +7y - 6y - 4 - 3y²
The first step is to group the terms of the equation into y² terms, y terms and terms with no y:
This gives, 6y² -3y<...

Okay so what this question is asking for is 4 lots of 1/5 of 60.
So our first step is the find 1/5 of 60 and we do this by dividing by 5. If you don't know your 5 times table off the top of your head...

Firstly we need to make sure we understand the question and do this by defining the key elements:
Prime number: A number that can only be divided by itself and 1 to give a whole numb...
