The equation for a line can be written in the form y = mx + b, where m is the slope and b is the y-intercept.
Given that the line crosses the y-axis at (0,4) and has a slope of -2, we know that b = 4 and m = -2.
Therefore, the equation for this line is y = -2x + 4.
A line crosses the y-axis at (0,4) and has a slope of -2. Find an equation for this line.
