Question

Which of the following equations represents a line perpendicular to y = –2x + 4?

A. 2x + y = 3

B. –x + 2y = 1

C. 2x + y = 4

D. x + 2y = –4

Answer 1

Is B the correct answer?

Answer 2

Correct !

Answer 3

slope of given line = -2
lets say, slope of perp line = m

m*-2 = -1
m = 1/2

Answer 4

oly B has a slope of 1/2, so thats ur answer

Answer 5

uve done the same way or used a different method ?

Answer 6

same method but I wasnt sure if B was correct!
