What is the equation of the following graph?

here we have graph which is the shape of parabola and a staright passing through y .

we know that general equal of parabola lies x axis

y=x^2

and the equation of straight line y=5

it means y=mx+b

where it is a straight line it does not have slope so m=0 x intercept is also 0 and y intercept is 5 .

if we plug these equation in straight line equation we get y=5

step-by-step explanation:

what is the figure? attach a picture.

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.
