His error is in step 3. The variable x is being multiplied by -7 and therefore he should have divided both sides by -7, not 7 as he did.
If you fold a piece of paper, it will have 2 rectangles.
If you fold it again, it will have 4 rectangles.
If you fold it again, it will have 8 rectangles.
So, if you fold it n times, it will have 2^n rectangles.

If your paper has 128 rectangles, you made
7 folds.
Based on the calculations, the equation of this parabola is equal to (x - 6)² = 16(y + 4).
<h3>How to determine the equation of this parabola?</h3>
Mathematically, the standard equation with the vertex for a parabola is given by:
(y - k)² = 4a(x - h) for horizontal parabola.
(x - h)² = 4a(y - k) for vertical parabola.
<u>where:</u>
By critically observing the points, we can deduce that both the focus and vertex lie on the same vertical line x = 6.
<u>Given the following data:</u>
Focus with points = (6, 2).
Vertex (h, k) = (6, –4).
<u>Note:</u> a = 2 - (-4) = 2 + 4 = 6.
Substituting the given parameters into the formula, we have;
(x - 6)² = 4 × 4(y - (-4))
(x - 6)² = 16(y + 4).

Hello! To graph this equation, we need to determine the y-intercept and slope of the equation.
y = 1/6x
There is no y-intercept stated in the equation, which means it is 0, and the line passes through the origin (0,0).
The slope is 1/6. To graph this, you can think of

The slope is rising 1 unit, and it is going 6 units to the right as the slope is increasing. Hope this helps! :)
