Let's take a look at D:   

<span>D)    y = (x-1)^2 - 16     Compare this to 
        y = (x-h)^2 + k       This is the std. equation of a parabola in vertex form.

You can see, by comparison, that h=1 and k= -16; these are the coordinates of the vertex, clearly shown in the diagram.

Since the coefficient of (x-h)^2 is +1, the graph opens upward (which the given graph confirms), and is neither compressed nor stretched vertically.</span>

Which equation represents a line which is parallel to the line 3x - y = 6?​
DochEvi [55]

Step-by-step explanation:

We just have to remember the line equation <u>y=mx+b</u> , then place the given equation into this form (y= -3x-6).

Remember that (m) is your slope. So, to find a parallel line, they must have an equal slope. Check the other equations and see which one had a slope of -3. The answer C also has a slope of -3. So those lines would be parallel.
