What is the slope of the line represented by the equation y = 8x + 4?

  1. 8

  2. -4

  3. 4

  4. 0

The correct answer is: 8

The slope of a line represents how steep or flat it is. In this equation, y = 8x + 4, the slope is the coefficient of x, which is 8. Therefore, the slope of this line is 8. Option B is incorrect because it represents the y-intercept of the line rather than the slope. The y-intercept is the point where the line crosses the y-axis, which is 4 in this equation. Option C is incorrect because it also represents the y-intercept rather than the slope. Option D is incorrect because the slope cannot be 0 as the line is not horizontal. The only time the slope would be 0 is if the line is perfectly flat or horizontal.
