    Hi does anyone know how to work out the gradient of each line when the equation is already done for you for example:

    y = 4x+3 y = 3+x

    In an equation of the form y=mx+c, the 'm' term is the gradient, the coefficient (the number next to the x) of x. So in your first one it would be 4 - what it is in the second one?

    It is very important that you have y on its own on one side, in this case it is already done, but for example if 2y= 3x + 4, the gradient is not 3, but you have to have y with a coefficient of 1 so you divide the whole equation by 2 to give a gradient of 3/2.
