    Step-by-step explanation:

    The equation of a straight line can be represented in the slope-intercept form, y = mx + c

    Where c = intercept

    Slope, m = change in value of y on the vertical axis / change in value of x on the horizontal axis

    change in the value of y = y2 - y1

    Change in value of x = x2 - x1

    y2 = final value of y

    y 1 = initial value of y

    x2 = final value of x

    x1 = initial value of x

    The slope of the line is 7 and it passes through (8,6).

    To determine the intercept, we would substitute x = 8, y = 6 and m = 7 into y = mx + c. It becomes

    6 = 7 * 8 + c

    c = 6 - 56 = - 50

    The equation becomes

    y = 7x - 50
