What is the equation of the line through (3,7) that is perpendicular to the line through points (-1,-2) and (5,3)?Please help :')
Accepted Solution
A:
the line through points (-1,-2) and (5,3) slope=(3-(-2))/(5-(-1))=5/6 for a perpendicular line slope =-6/5=-1.2 y=(-6/5)x+b 7=(-6/5)*3+b 7=-18/5+b 7=-36/10+b 7=-3.6+b b=10.6 y=-1.2x+10.6
