I need help with my math homework?
1. The points A and B have coordinates (-4, 6) and (2,8) respectively. A line p is drawn through B perpendicular to AB to meet the y-axis at the point C.
a. Find an equation of the line p.
b. Determine the coordinates of C.
2 The line l has equation 2x -y-1=0.
The line m passes through the point A (0,4) and is perpendicular to the line l.
a. Find an equation of m and show that the lines l and m intersect at the point p (2,3). The line n passes through the point B(3,0) and is parallel to the line m.
b. Find an equation of n and hence find the coordinates of the point Q where the lines l and n intersect.
