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

Which equations and/or functions represent the graphed line? Check all that apply.
8090 [49]
The picture in the attached figure

step 1

find the equation of the line of the graph

let
A (-4,0)  B(0,2)

slope m=(y2-y1)/(x2-x1)------> m=(2-0)/(0+4)----> m=1/2----> m=0.5

with m=0.5 and point B (0,2)
y-y1=m*(x-x1)-----> y-2=(0.5)*(x-0)-----> y=0.5x+2


step 2
find the solution
<span>
a) f(x) = 0.2x - 4----> the </span>function not represent  the graphed line<span>
b) f(x) = 0.5x + 2----> </span> the function represent  the graphed line<span>
c) f(x) = x + 2</span>--> the function not  represent the graphed line<span>
d) y – 3 = (x – 2)---> y=x+1---> </span>the function not represent the graphed line<span>
e) y – 1 = 0.5(x + 2)</span>-----> y=0.5x+1+1---> y=0.5x+2----->  the function represent  the graphed line

therefore

the answer is
<span>f(x) = 0.5x + 2
and
</span>y – 1 = 0.5(x + 2)
