    Answer:

    The four points that appear on the line are:

    B- (0,-9)

    D-(9,-3)

    E-(6,-5)

    F-(3,-7)

    Step-by-step explanation:

    The equation of the line in slope-intercept form is:

    y = mx + b

    Being m the slope and b the y-intercept.

    We are given the values of m=2/3 and b=-9, so the equation of the line is:

    y = 2/3 x – 9

    We must select from the list below the points that lie on the line. To test each point, we substitute the value of x and calculate the value of y. If it matches the given y-coordinate, then the point lies on the line.

    • A- (2,3)

    Calculate: y = 2/3 (2) – 9 = -23/3.

    This point is not on the line because -23/3 ≠ 3

    • B- (0,-9)

    Calculate: y = 2/3 (0) – 9 = -9.

    This point is on the line because -9 = -9

    • C- (1,9)

    Calculate: y = 2/3 (1) – 9 = -25/3.

    This point is not on the line, because -25/3 ≠ 3

    • D-(9,-3)

    Calculate: y = 2/3 (9) – 9 = -3.

    This point is on the line because -3 = -3

    • E-(6,-5)

    Calculate: y = 2/3 (6) – 9 = -5.

    This point is on the line because -5 = -5

    • F-(3,-7)

    Calculate: y = 2/3 (3) – 9 = -7.

    This point is on the line because -7 = -7

    The four points that appear on the line are:

    B- (0,-9)

    D-(9,-3)

    E-(6,-5)

    F-(3,-7)
