C)
The gradient of the line is
1/3.
D)
The equation of the line is y = −3x.
E)
The equation of the line is y =2x − 6.
F)
The line cuts the y-axis at y =3.
G)
The line passes through the origin.
H)
The line passes through the point (1, −1).

    (−1, 3) and (2, −6)

    (-6 -3)/(2+1) = slope(or gradient) = -9/3 = -3
    therefore
    y = -3 x + b
    3 = -3(-1) + b
    b = 0
    so
    y = -3x
    this goes through (0,0)
