Answer:
r = 
Step-by-step explanation:
The distance from the centre to a point on the circle is the radius r
Calculate r using the distance formula
r = 
with (x₁, y₁ ) = (0, 0 ) and (x₂, y₂ ) = (2, 5 )
r = 
= 
= 
= 
Every proportional relationship is an equation like y = a number times 'x'. When you graph that equation it's a straight line that goes through the origin and every point on the line satisfies the equation. Line B is the only graph that looks like that. The others all have a piece of a proportional relationship. Their bottom pieces are proportional relationships but then they break and the top pieces are not.
