    Answer:

    y = -2x -7

    Step-by-step explanation:

    m = -2

    y-intercept = -7

    In y=mx+b (slope intercept form) ,

    m = slope

    b =y-intercept

    Substitute the given values into  slope intercept form

    y = -2x -7

    Answer:

    y = -2x – 7

    Step-by-step explanation:

    The general formula of a linear graph is y = mx + c

    where m is the gradient and c is the y-intercept

    The slope (aka gradient) is -2, hence m= -2

    and the y-intercept is -7, hence c = -7

    Therefore, y = -2x + (-7)

                      y = -2x – 7
