To find the reflection point of the y-intercept, we focus on the x-coordinates. The distance between the vertex's x-coordinate and the x-coordinate of the y-intercept is the same distance between the vertex's x-coordinate and the desired point's x-coordinate. This is because the vertex acts as an axis of symmetry.

The vertex of the parabola is (-7, -2). The y-intercept is (0, 145).

The distance between the two x-coordinates is 7. Therefore, the x-coordinate of the reflection point is -14.

Evaluate y when x=-14 to find the reflection point.
