Given:
The equation of the parabola is:

To find:
The y-intercept of the parabola.
Solution:
We have,

Putting
in the given equation, we get



Therefore, the y-intercept of the parabola is 0. It means the y-intercept of the given parabola is at point (0,0).
In the second equation it is actually going on to be +2x^2 -4x-2 then your going to combine like terms. So it will be 5x^2-10. Because he 4x’s are going to eliminate each other.
Answer:

Step-by-step explanation:
The formula of a slope:

We have the points (2, 3) and (-4, 12).
Substitute:
