The function is given by the formula y = 4x-30 whether the graph of the function passes through point B (7; -3).

In order to determine whether the graph of the function passes through the point B (7; -3), we substitute its coordinates into the formula and check the equality. Then in the formula y = – 3, and x = 7. Substitute the values into the formula and check:
-3 = 4 * 7 – 30;
-3 = 28 – 30;
-3 = -2;
-3 ≠ -2;
Answer: the graph of the function does not go through point B.
