Since the line passes through the y-axis at (0,4), the y-intercept is 4. The slope of the line is -2.

Using the point-slope form of a linear equation, y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope, we can substitute the values into the equation:

y - 4 = -2(x - 0)

Simplifying,

y - 4 = -2x

Adding 4 to both sides,

y = -2x + 4

Therefore, the equation for this line is y = -2x + 4.
