# Does the graph of the function y = -2.4x-5 belong to the following points: A (0; -5) B (-1; 4) C (-2; 0.2) D (1; -7.4)

| To solve the problem, we substitute the coordinates of the points into the equation of the straight line:

-2.4 * 0 – 5 = -5,

-5 = – 5,

then the graph goes through point A.

-2.4 * (-1) – 5 = -2.6,

-2.6 ≠ 4,

then point B does not belong to the schedule.

-2.4 * (-2) – 5 = -0.2,

-0.2 ≠ 0.2,

accordingly, the graph of the function does not pass through point C.

-2.4 * 1 – 5 = -7.4,

-7.4 = (-7.4),

Thus, point D. belongs to the graph of the function.

Answer: the graph of the function y = -2.4x-5 passes through the points: A (0; -5) and D (1; -7.4). Points B (-1; 4) and C (-2; 0.2) do not belong to the graph of the function.
