Question 679711: I am asked to find line parallel with only the following problem:
y = -1/2x + 1 (4,2)-the ordered pair
I am asked to find perpendicular line with following problem:
y = -3x - 6 (-1, 5)-ordered pair

Parallel lines have the same slope
Use the slope of -1%2F2 and the point (4,2)
y - 2 = -1%2F2(x-4)}}}
y-2 = %28-1%2F2%29x+%2B+%281%2F2%29%284%29
y - 2 = %28-1%2F2%29x+%2B+2

...
Perpendicular lines have the negative reciprocal slope
Use the slope of 1%2F3 and the point(-1,5)
y - 5 = 1%2F3(x--1)
y - 5 = %281%2F3%29x+%2B+%281%2F3%29
y = %281%2F3%29x+%2B+%281%2F3%29+%2B+5%283%2F3%29
highlight_green%28y+=%281%2F3%29x+%2B+16%2F3%29
