Question

I really need help Select the equation of a line that is perpendicular to the line on the graph and passes through the point (-1, 2).

Answers:
y = 2x + 4

y = - 2x + 2

y = - 1 over 2 x + 2

y = 2x - 1

Answer 1

what is question?

Answer 2

I posted the attachment

Answer 3

first equation of line is y =(-1/2)x-1
The slope of the perpendicular line is 2
y=2x+a so (x=-1,y=2) a=4
then y=2x+4
