In slope-intercept form :
1. Perpendicular to y= 3/4x - 2 and passes through (-12,7).
2. Perpendicular to the y-axis and passes through (-2,5).
3. Find the coordinates of the midpoint of the line segment with endpoints (-3,6) and (-1,-9).
4. P is the midpoint of the line segment AB. The coordinates of P are (5,-6). The coordinates of A are (-1,10). Find the coordinates of B.
5. A carpenter is building a stairway. The depth of each tread is 10 inches. The height of each riser is 8 inches. What is the steepness (slope) of the stairway?
6. The endpoints of AB are A (-4,8) and B (12,-4). Find the coordinates of P if P lies on AB and is 3/8 the distance from A to B.
7. Find the equation in slope-intercept form of the line that is perpendicular to AB and passes through the midpoint of AB. Let
A = (-6,2) and B = (4,-10).
