# Answer to Question #22801 in Trigonometry for Kristen Woods

Question #22801

Find the slope of the line that is a) parallel and b) perpendicular to the given line.

12. x=-8

13. y=10

12. x=-8

13. y=10

Expert's answer

x=-8

x+8 = 0

0*y = x+8

y = (1/0)x +8/0

a) k1=1/0 -& undefined slope

b) k1*k2 = 1

k2 = 1/k1 = 0/1 = 0

Answer: a)& undefined slope, b) 0

y = 10

y = 0*x + 10

a) slope - k1 = 0

b) k2 = 1/k1& -& undefined slope

Answer: a) 0,& b)& undefined slope

x+8 = 0

0*y = x+8

y = (1/0)x +8/0

a) k1=1/0 -& undefined slope

b) k1*k2 = 1

k2 = 1/k1 = 0/1 = 0

Answer: a)& undefined slope, b) 0

y = 10

y = 0*x + 10

a) slope - k1 = 0

b) k2 = 1/k1& -& undefined slope

Answer: a) 0,& b)& undefined slope
