Describe how the graph of the equation y = x – 4 would change if the equation was changed to y = x + 4. A
The new line would be parallel to the original line.
B
The new line would be perpendicular to the original line.
C
The new line will have the same x-intercept.
D
The new line will be the exactly the same as the old line.

I believe A

Since everything is the same except the symbol they should be parallel.

Hope this Helps!

answer:

c. the third graph

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
