  1. Recall the point-slope form:
    y - y1 = m(x - x1)
    where
    (x1, y1) = a point on the line
    m = slope or the gradient
    In the problem, we have a gradient or slope = 3, and point (-3,3) on the line.
    Substituting,
    y - 3 = 3(x - (-3))
    y - 3 = 3(x + 3)
    y = 3x + 9 + 3
    y = 3x + 12
    Note that this form is the slope-intercept form (y = mx + b).
    In the equation we got, the slope (m) is 3, and the y-intercept (b) is 12.

    Hope this helps~ :)
