What is the y-intercept of the line 4x + 8 = 0?

0
8
-8
4

The correct answer is: 8

In order to find the y-intercept of a line, we need to use the slope-intercept form of a line, y = mx + b, where m is the slope of the line and b is the y-intercept. In this given equation, we can rewrite it in the slope-intercept form by subtracting 4x from both sides, giving us y = -4x + 8. This means that the slope of the line is -4 and the y-intercept is 8. Therefore, the correct answer is B. Option A is incorrect because it represents the y-coordinate of the x-intercept, which would be 0 in this case. Option C is incorrect because it represents the negative y-value of the y-intercept, which is incorrect according to the slope-intercept form of a line. Option D is incorrect because it represents the slope of the line
