1. Substitute the coordinates of the point A (-1; 5) into the equation of the straight line:

x = -1;
y = 5;
y = 3x + m;
5 = 3 * (-1) + m;
5 = -3 + m;
m = 5 + 3;
m = 8.
2. The straight line y = 3x + m passes through point A at m = 8. In this case, we obtain the equation:

y = 3x + 8.

Answer. With parameter value: m = 8.
