What set of reflections would carry rectangle ABCD onto itself?
Furkat [3]
Answer: option <span>D) y=x, x-axis, y=x, y-axis</span>.

I first thought it was the option C) and I tried with it but it was wrong. This is how I dit it.

Option C step by step:

<span>1) Reflection over the x - axis => point with coordinates (a,b) is transformed into point with coordinates (a, -b)

2) Reflection over the line y = x  => point with coordinates (a, -b) is transformed into point with coordinates (-b,a)

3) New feflection over the x - axis => (-b,a) transforms into (-b, -a)

4) New reflection over the line y = x => (-b,-a) transforms into (-a,-b)

Which shows it is not the option C).

Then I probed with option D. Step by step:

1) Reflection over the line y = x => (a,b) → (b,a)

2) Reflection over the x-axis => (b,a) → (b,-a)

3) Reflection over the line y = x => (b,-a) → (-a,b)

4) Reflection over the y-axis => (-a,b) → (a,b).

So, this set of reflections, given by the option D) transforms any point into itself, which proofs that the option D) is the right answer.

Answer:

\huge\boxed{y=6x+9}

Step-by-step explanation:

In order to put this equation into slope-intercept form, we want to get this into the form y=mx+b, where m is the slope (coefficient) and b is the y-intercept.

We already have the equation y-6x=9. Looking at this equation, we can see that we have to get 6x off the left side of the equation and on to the right.

To do this, we can add 6x to both sides. However, if we add 6x to one side we must add it to the other.

So, let’s add 6x to both sides.

y -6x + 6x = 9 + 6x

y = 9 + 6x

We can now rearrange the terms.

y = 6x+9

Hope this helped!
