Answer:

first question: c. x = 1

6. B. y = -2x - 8

Step-by-step explanation:

first question:

perpendicular means that when it intersects, it makes a right angle.

the equation y = 5 would be parallel to any of the answers with y = ___ because all of those would result in horizontal lines

either of the x = ___ would be perpendicular to y = 5

since it has to pass through the point (1,3) that means that the equation must be x = 1

the equation x = 1 passes through any point beginning with (1 , _)

6.

parallel means that the equations have the same slope. therefore, we can eliminate both A and C

using the given point (-2 , -4),we can plug into the y = mx + b format to solve

m = -2   x = -2   y = -4

-4 = (-2)(-2) + b --> -4 = 4 + b --> b = -8

finally, our equation comes out to be y = -2x - 8
