The graph of the function y = kx passes through point A (-3; 6).

y = kx is the general equation of the straight line.

Point A has coordinates of the general form (x; y), we substitute x and y into our general equation of the straight line and get:

Substitute the coordinate values at point A:

6 = k * (-3). Let us express k from this expression.

k = 6 / -3 = -2.

The answer is k = -2.
