Please help me with this question
2 answers:
(x+a)^2+(y+b)^2=r^2 where (-a,-b) is the center and r is the radius.
(x+4)^2+(y+1)^2= 9
so the answer is D
remember when solving for radius in this formula and need to graph, you have to square root

Answer: the slope is 2
Explanation:
The graph goes up 2 and over 1. When finding slope the formula is rise/run
Answer:
y intercept is 13
Step-by-step explanation:
y - 3 = 2(x + 5)
To find the y intercept, let x=0 and solve for y
y - 3 = 2(0 + 5)
y - 3 = 2(5)
y -3 =10
y-3+3 = 10+3
y = 13
