SOLUTION: Find equations in standard form of the line through point p that are a) parallel and b)perpendicular to line L P(2,0); L :x + 2y = 3

Question 1065575: Find equations in standard form of the line through point p that are a) parallel and b)perpendicular to line L
P(2,0); L :x + 2y = 3

line L P(2,0); L : x + 2y = 3
L in slope-int form:: y = (-1/2)x + (3/2)
----------------------------
Find equations in standard form of the line through point P that are
a) parallel to L
slope = -1/2
Form:: y = mx + b
Since it goes through P, 0 = (-1/2)2 + b
b = 1
Ans: y = (-1/2)x + 1
----------------------------------
and b)perpendicular to L
slope = 2
Form:: y = mx + b
0 = 2(2) + b
b = -4
---
Ans:: y = 2x - 4
