In the equation of the parabola, the value for p represents the distance between the vertex and the focus. To find it, use the formula to find the distance between 2 points:
![\begin{gathered} d=√((y2-y1)^2+(x2-x1)^2) \\ d=\sqrt{(2-2)^2+(-(31)/(16)-(-2))^2} \\ d=\sqrt{(-(31)/(16)+2)^2} \\ d=\sqrt{((1)/(16))^2} \\ d=(1)/(16) \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/3n3qq38j9q2rzqyaq10k5v2f46qdoeset5.png)
It means that the value of p is 1/16, in decimal form, 0.0625.
The value of h is the x coordinate of the vertex, which is -2.
The value of k is the y coordinate of the vertex, which is 2.
