The line of symmetry for the quadratic equation y=ax^2+8x-3 is x=4. What is the value of “a”?

The value of a is -1.

Step-by-step explanation:

The line of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves.

For a quadratic function in standard form, , the line of symmetry is a vertical line given by .

We know that the quadratic equation, , has x = 4 as line of symmetry. Therefore, the value of a is:
