Final answer:
The slope-intercept equation of the line is y = -3.
Step-by-step explanation:
To find the slope-intercept equation of the line that passes through (-6, -3) and has a slope of 0, we can use the formula y = mx + b, where m represents the slope and b represents the y-intercept.
Since the slope is 0, the equation becomes y = 0x + b, which simplifies to y = b.
Since the line passes through (-6, -3), we substitute these values into the equation: -3 = b. Therefore, the slope-intercept equation of the line is y = -3.
