Final answer:
The slope-intercept form of the equation is y = mx + b, where m is the slope and b is the y-intercept.
Step-by-step explanation:
The slope-intercept form of an equation is y = mx + b, where m is the slope and b is the y-intercept.
For the given equation, y = 8x + 4, the slope is 8 and the y-intercept is 4.
Therefore, the slope-intercept form of this equation is y = 8x + 4.
