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
The picture in the attached figure
step 1find 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 2find 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 + 2and</span>
y – 1 = 0.5(x + 2)
