The one big **difference between** the two smartphones is the display. Where the Redmi **Y1** featured a 5.5-inch HD display, the Redmi **Y2** flaunts a more contemporary 5.99-inch HD+ display with 18:9 aspect ratio. While both devices feature the same memory options, Xiaomi has upgraded the chipset powering the devices.

**Read remaining answer here. Similarly, how do you know which one is y1 and y2?**

**Example**

**Beside above, does it matter which is x1 and x2? If you have two pairs (x1, y1) and (x2, y2) and both pairs are solutions to a system of equations, it may be that their order matters, and either could be called (x1, y1) and the other called (x2, y2), or it may be that the order doesn’t matter.**

Regarding this, what is y2 y1 x2 x1 called?

## How do you find a slope in math?

The **slope** of a line characterizes the direction of a line. To find the **slope**, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .

What is the slope of a horizontal line?

**Horizontal lines** have a **slope** of 0. Thus, in the **slope**-intercept equation y = mx + b, m = 0.

### Is slope positive or negative?

A higher **positive slope** means a steeper upward tilt to the line, while a smaller **positive slope** means a flatter upward tilt to the line. A **negative slope** that is larger in absolute value (that is, more **negative**) means a steeper downward tilt to the line. A **slope** of zero is a horizontal flat line.

### What is a slope in math terms?

One of the most important things to understand about lines is the definition of **slope**. **Slope** is the ‘steepness’ of the line, also commonly known as rise over run. We can calculate **slope** by dividing the change in the y-value between two points over the change in the x-value.

### How do you find y intercept?

To find the **y intercept** using the equation of the line, plug in 0 for the x variable and solve for **y**. If the equation is written in the slope-**intercept** form, plug in the slope and the x and **y** coordinates for a point on the line to solve for **y**.

### What is Y MX B?

In the equation of a straight line (when the equation is written as “**y** = **mx** + **b**“), the slope is the number “m” that is multiplied on the x, and “**b**” is the **y**-intercept (that is, the point where the line crosses the vertical **y**-axis). This useful form of the line equation is sensibly named the “slope-intercept form”.

### How do you find slope without graphing?

You’ve seen that you can **find** the **slope** of a line on a **graph** by measuring the rise and the run. You can also **find** the **slope** of a straight line **without** its **graph** if you know the coordinates of any two points on that line. Every point has a set of coordinates: an x-value and a y-value, written as an ordered pair (x, y).

### What is Y intercept in math?

Every straight line can be represented by an equation: **y** = mx + b. The equation of any straight line, called a linear equation, can be written as: **y** = mx + b, where m is the slope of the line and b is the **y**–**intercept**. The **y**–**intercept** of this line is the value of **y** at the point where the line crosses the **y** axis.

### What is the slope intercept form?

The **slope**–**intercept form** of the equation of a line is y = mx + b, where m is the **slope** of the line, and b is the y-**intercept**. Since we are given two points, we can calculate the **slope** m as follows: Note that the **slope** is the same if we interchange the order of the points.
