Answer:
y =
x
Step-by-step explanation:
The equation of a line passing through the origin is
y = mx ( where m is the slope )
Here m =
, thus
y =
x ← equation of line
Start with the given formula for the surface area of a sphere.

Now substitute 2x + 5 in for r, the radius.
Then simplify the expression and write it in standard form.


The answer is x<-1. hope this helps.
