Final answer:
The slope-intercept form of the given equation is y = 1/6x + 2, the slope is 1/6, the equation of a parallel line passing through (6, 10) is y = 1/6x + 9, and the slope of the perpendicular line is -6.
Step-by-step explanation:
1. To rewrite the equation -x + 6y = 12 in slope-intercept form, solve for y. This gives us y = x/6 + 2 or y = 1/6x + 2. In slope-intercept form, the equation is y = mx + b where m is the slope and b is the y-intercept.
2. The slope of the line is the coefficient of x, which is 1/6.
3. A line parallel to the given line will have the same slope, so the slope is 1/6. The equation of this line can be found using the point-slope form, which is y - y1 = m(x - x1). Substituting the point (6, 10) and slope 1/6, we get y - 10 = 1/6(x - 6). To rewrite in slope-intercept form, simplify to get y = 1/6x + 9.
4. The slope of a line perpendicular to a given line is the negative reciprocal of the original slope. Therefore, the slope of the perpendicular line is -6.
