Question

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

2x + y = 3

B. –x + 2y = 1

C. 2x + y = 4

D. x + 2y = –4

Answer 1

@RH when two lines are perpendicular , product of their slopes is equal to -1
use this concept

Answer 2

so the answer is D ? Since the product is negative...

Answer 3

no if u chose D product of slopes would be positive
remember slope intercept equation y = mx+c
compare with this form and solve

Answer 4

Hmm... so the right answer would be B?

Answer 5

yeah answer would be B
:-)

Answer 6

Thank you!
