Final answer:
The slope-intercept form of the equation 18x + 3y = -18 is y = -6x - 6, where the slope is -6, and the y-intercept is -6.
Step-by-step explanation:
The equation 18x + 3y = -18 can be converted to slope-intercept form, which is y = mx + b, where m represents the slope of the line, and b is the y-intercept. To find the slope-intercept form, we need to solve for y:
- 18x + 3y = -18
- 3y = -18x - 18
- y = (-18x - 18) / 3
- y = -6x - 6
Therefore, the slope-intercept form of the line is y = -6x - 6. Here, the slope (m) is -6, and the y-intercept (b) is -6.
