Answer:
2x - y = -7
Step-by-step explanation:
The equation y = 2x+7 needs to be written in standard form 
where A must be positive.
To convert to standard form, subtract 2x from both sides.
-2x + y = 7
Multiply each term by -1.
-1(-2x + y =7)
2x - y = -7
Answer:
(x+2.3)^2 + (y) ^2 = (6/7)^2
Step-by-step explanation:
The equation of a circle can be written as
(x-h)^2 + (y-k) ^2 = r^2 where ( h,k) is the center and r is the radius
(x- -2.3)^2 + (y-0) ^2 = (6/7)^2
(x+2.3)^2 + (y) ^2 = (6/7)^2
