    The line joining (c,4) to (7,6) has a gradient -1/4
    q) work out value of d

    so I did 6-4 over 7-c which = -1/4

    2 over 7-c = -1/4

    How did get of the division? x but what?

    x
    Multiply both sides by (7-c). You can do anything in maths so long as you do it to both sides of the equation.
