Question

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

y = 2x + 4

y = - 2x + 2

y = - 1 over 2 x + 2

y = 2x - 1

Answer 1

Answer 2

Just a sec

Answer 3

k thx

Answer 4

find eqn of the line on the graph, y = mx + b

perpendicular means slope of new line will be (-1/m)

use y' = (-1/m) + b' to find the new line, substituting (-1,2) to find b'

Answer 5

?

Answer 6

I got A so y=2x+4

Answer 7

thank you so much novalynne
