Answer:

Step-by-step explanation:
we know that
The quadratic equation
is a vertical parabola
The axis of symmetry in a vertical parabola is a vertical line
The equation of the axis of symmetry in a vertical parabola is equal to the x-coordinate of the vertex
The x-coordinate of the vertex is equal to the formula

therefore
the equation of the axis of symmetry is equal to

Answer:
-0.2
Step-by-step explanation:
Simplifying
5x = 3y + -4
Reorder the terms:
5x = -4 + 3y
Solving
5x = -4 + 3y
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '5'.
x = -0.8 + 0.6y
Simplifying
x = -0.8 + 0.6y
