# Changes in Our Eyes's Numbers

### Myopia and How It Affects a Person's Eye Number...

## By: Mahak Gandre

## The Comparison

My cousin, Aishwarya has an eye illness called myopia. This illness makes the number of your eyes worsen over the years. So I decided to ask her to tell me her eye prescription, an according to her prescription I researched another. One who has myopia over the age of 16, know that their number steadily increases, by a specific interval. So I decided to compare my cousin's and another person's eye number for their myopia. The data is recorded over the course of ten years, and it shows the steady decrease in each person's number over those years.

## The Data Collected

## Variables

## The Equations

**Aishwarya's Data:**

To Find the Equation:

1. Look at the first difference: It is -0.75 or -3/4

2. The first difference of -3/4 is the slope, so that is value of *m. *

3. The value of *b *is 0, so there is no *b* value.

Using this information, we can use it to create the equations.

The equation in the form of y-intercept and slope is*y = -3/4x.*The standard form for this equation would be

*3x + 4y + 0 = 0.*

**Individual's Data:**

To Find the Equation:

1. Look at the first difference: It is -0.5 or -1/2

2. The first difference of -1/2 is the slope, so that is value of *m. *

3. The value of *b *is -1.5, so that is the value of *b.*

Using this information, we can use it to create the equations.

The equation in the form of y-intercept and slope is *y = -1/2x - 3/2.* The standard form for this equation would be *x + 2y + 1.5 = 0.*

## The Graph

## Intersection

*x*as its value and -4.5, will substitute

*y*for its value.

**First Equation: Aishwarya's Equation:** *y = -3/4x*

y = - 3/4x

- 4.5 = - 3/4 (6)

- 4.5 = - 18/4

- 4.5 = - 4.5

As the two sides equal to each other, it means that this point surely runs along this line.

**Second Equation: Mahak's Equation:** *y = -1/2x - 3/2*

y = - 1/2x - 3/2

- 4.5 = - 1/2 (6) - 3/2

- 4.5 = - 6/2 - 3/2

- 4.5 = - 9/2

- 4.5 = - 4.5

As the two sides equal to each other, it means that this point surely runs along this line.

As the point falls on both lines, it means that these lines do intersect, because to intersect to lines have to have the same coordinate have a place both of them. These two lines do have a point which falls on both of them, the point being (6, -4.5)

## The Significance Behind this Topic...Myopia

The significance behind the topic of this flyer is to inform one about the seriousness of the illness, myopia, and the toll it can take on a person's eyes. The effect of myopia is that the number of one's eye increases rapidly, and that it can lead to blindness. Currently, my cousin's eye number is in between -9 and -10. Much worse than this can occur and has occurred to some individuals or is occurring to them currently. My goal was to inform you of this illness and let one see what can happen to someone with myopia. If you want to know, imagine this, everything for you is completely blurry, only strange blobs or colour or even darkness can be seen. This is what they see every time they don't have their glasses or contacts on.
