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

slope of y=-2x+4 is ?

Answer 2

The answer is B. Use GeoGebra. Its a free download and my Algebra 2 teacher requires it. It will help a lot.

Answer 3

The slope is -2

Answer 4

slope of perpendicular line is reciprocal inverse,
so, m = -1 /(-2) =1/2
gotthis ?

Answer 5

yes

Answer 6

so, the equation will be of the form,
y=mx+c
or y=(1/2)x+c
or you can determine which line has slope =1/2

Answer 7

hmm... I am kind of confused but is the correct answer D?

Answer 8

no...

Answer 9

Is it B?
