    Answer: y = 2x – 13

    Explanation:

    Slope intercept form: y = mx + c where m is the gradient/slope (how steep the line is) and c is the y intercept ( the point where the line crosses the y axis)

    It states parallel, so you know that the gradient has to be the same (they need to be “steep” at the same rate to be parallel)

    Substitute the numbers in:

    y = mx + c

    -5 = 2(4) + c

    -5 = 8 + c

    c = -8-5

    c = -13

    With this, rewrite the equation:

    y = 2x – 13
