Which of the following is the equation of a line perpendicular to
4y = 2x + 5 that passes through (-1, -1)?
A.
y - 2x = -3
B.
2y - 2x = 10
C.
y = -2x - 3
D.
y = -2x - 6

Step-by-step explanation:

Two lines are said to be perpendicular if the product of their slope = -1

Given :

to find the slope , we will write it in the form :

That is

which means that the slope =

any line that is perpendicular to this line will have slope = -2

using the formula :

, we have

f(x) = y

f(-3) = -5
