The equation f(x)= 2x-9 translate 6 units up is g(x)=

Btw I got this answer from gauth math
2x -3

Explanation
Solution: Move the straight line and its slope, remains unchanged, and y-axis focus change

X^2 - 4x +(4/2^2) + y^2 + 8y + (8/2^2) = -4 + (4/2^2) + (8/2^2)(x + 2)^2 + (y + 4)^2 = -4 + 4 + 16your center is (-2, -4) and the radius is the sqrt of -4 + 4 + 16 which is 4
