Your equation is:
x² + y² = 15
Answer:
The equation of line is y+2=0
Step-by-step explanation:
The equation of line passing through the point
and having slope m is

Given slope m=0 and given point is is (-2,-2)


therefore equation of the straight line is 
Therefore the straight is parallel to negative x-axis(y=-2)
Can you please explain a little more i’m not fully understanding

Answer:
141.78 m
Step-by-step explanation:
