The line of symmetry for the quadratic equation y = ax2 - 8x - 3 is x = 2. what is the value of \"a\"? . -2. -1. 3

The value of a is 2

Step-by-step explanation:

The quadratic equation is

The line of symmetry is x =2.

We know that the graph of quadratic function is a parabola and the line of symmetry of a parabola always passes through the vertex.

The line of symmetry is x =2.

And the x-coordinate of the vertex is

Hence, we have

Thus, the value of a is 2

the correct answers i think are b. and d.

give me brainliest if it is correct!

it's a proportional graph.

step-by-step explanation:

8 x 5 = 40         (and you have -8x and -5y)

x= absiss

y= orderly

so you have a proportional graph.
