Answer: The correct option is

(B) The vertex is (6, 3), and the axis of symmetry is x = 6.

Step-by-step explanation: We are given to find the vertex and the axis of symmetry of the graphed quadratic equation.

From the graph, we see that the graphed quadratic function is a parabola, which open downwards and maximum point is (6, 3).

So, the vertex of the parabola is at (6, 3).

Now, the axis of symmetry will be a line passing through the vertex and parallel to the Y-axis.

That is, x = k.

Since the axis of symmetry passes through the vertex (6, 3), so we get

x = 6.

Thus, the vertex is (6, 3), and the axis of symmetry is x = 6.

Option (B) is CORRECT.

Answer:

D is correct

Step-by-step explanation:

A graph of that sort will make a perfectly mirrored "V" shape, and with no offset, the bottom point will be on the y axis. This means that the first equation will intercept the y axis at zero, the second will intercept the y-axis at -15.

"A" may seem correct also, as the second graph will intercept the x-axis at -15, but it is not complete, as it will intercept that axis at +15 as well.

Someone please convert this equation to slope intercept form: 2x - 3y = 6?

IgorLugansk [536]

Slope y-intercept form is: y=mx+b

All you have to do is rearrange the equation:

2x-3y=6
2x=6+3y
2x-6=3y

now divide both sides by 3
(2x/3)-(6/3)=(3y/3)

and it becomes
$y= \frac{2}{3}x-2$ x

Bonus: you can plug in any two values for x and y and you can see both equation gives the same answer!
