The equation for a parabola does become \rm x^2=4py.

<h3>What is parabola?</h3>

A symmetrical open plane curve formed by the intersection of a cone with a plane parallel to its side. The path of a projectile under the influence of gravity follows a curve of this shape.

Given

The derivation for the equation of a parabola with a vertex at the oriin.

The equation of the parabola can be written as;

\rm  (x)^2 + (y - p)^2 = (0)2 + (y + p)2\\\\x^2 + y^2 - 2py + p^2 = y^2 + 2py + p^2\\\\ x^2= 2py+2py\\ \rm \\x^2=4py

Hence, the equation for a parabola does become \rm x^2=4py.

What is the slope of the linear table below?
Luden [163]

Answer:

A

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 3, 8) and (x₂, y₂ ) = (0, 10) ← 2 ordered pairs from the table

m = \frac{10-8}{0+3} = \frac{2}{3} → A
