## The Lesson

The slope of a line is its steepness. It is how far up a line goes compared to how far across it goes. The line below has a slope of**2**because it goes up 2 units for every 1 unit it goes across. A line can be represented by a linear equation. We can find the slope from a linear equation.

## Real Examples of Finding the Slope from a Linear Equation

Finding the slope of a line from a linear equation is easy. Here are some linear equations, which represent lines. We show how to find the slope from the linear equation.-
The slope of
**y = 2x + 1**is**2**. Look at the number in front of the**x**(called the coefficient of x). This is the slope. A slope of 2 means that the line will go up by 2 when it goes across by 1. -
The slope of
**y = −3x + 3**is**−3**. The number in front of the x is negative. This means the line slopes**downwards**. A slope of −3 means that the line will go down by 3 when it goes across by 1. -
**y = 2**is a horizontal line. It has a slope of**0**.**y = 2**does not have an**x**in it. We can imagine there is an invisible**0**in front of the x which gets rid of it. A slope of 0 means that the line will neither go up nor down when it goes across by 1.
