Answer in slope intercept form (y =mx +b)

what is the equation of a line that is perpendicular to 2x + y = -4 and passes through the point (2, -8) you so much!

y = - 9

Step-by-step explanation:

Two lines are said to be perpendicular if the product of their slope = 1 , that is , if the slope of the first line is and the slope of the second line is   , then   = , that is :

X   = -1

The line given is ; 2x + y = - 4

Make y the subject of the formula so that the equation will be in slope - intercept form ; y = mx + c

that is

y = -2x - 4

comparing with the equation of line y = mx + c , it shows that   = -2

Since the second line is perpendicular to this line , it means   =

That is

=

Using the formula y - = m ( x - ) to find the equation of the line

= -8

= 2

substituting into the equation

y - (-8) = ( x - 2)

y + 8 = ( x- 2)

2(y+8) = x - 2

2y + 16 = x - 2

2y = x - 2 - 16

2y = x - 18

y = - 18/2

y = - 9
