Use completion of sq method
x^2+y^2+14x+10y-7=0
(x+7)^2+(y+5)^2=7+49+25
(x+7)^2+(y+5)^2=81
so centre is(-7,-5) radius is9
Answer:
A because it has both the slope and the y-intercept
Answer:
graph your y intercept at negative 8 and then continue to go up one right one
V(s) = s^3 should be the correct answer. Hope this Helps!
