What is the Slope Intercept Form?

The slope-intercept form is a special form of the equation of a straight line. It is one of the most commonly used linear equations because of its straightforwardness in expressing both the slope of the line and its y-intercept.

The slope-intercept form of the equation is given by the following formula:

$$y=mx+b,$$

where:

• $$$y$$$ is the dependent variable, typically representing the vertical coordinate.
• $$$x$$$ is the independent variable, typically representing the horizontal coordinate.
• $$$m$$$ is the slope of the line. It defines the rate of change of $$$y$$$ with respect to $$$x$$$. In geometric terms, the slope represents the rise over the run, or how much $$$y$$$ changes per unit change in $$$x$$$.
• $$$b$$$ is the y-intercept. This is the point where the line crosses the y-axis. In simpler terms, it's the value of $$$y$$$ when $$$x$$$ is zero.

This equation provides valuable information about the line it represents:

• Slope $$$(m)$$$: The slope measures how steep the line is. It is the "rise" over the "run", mathematically represented as the change in the $$$y$$$ over the change in the $$$x$$$.

  The formula for the slope, given two points $$$\left(x_1,y_1\right)$$$ and $$$\left(x_1,y_1\right)$$$ is

  $$m=\frac{y_2-y_1}{x_2-x_1}$$

  For example, if we have the points $$$(2,3)$$$ and (4,7)$$$, the slope is

  $$m=\frac{7-3}{4-2}=\frac{4}{2}=2$$
• Y-intercept $$$(b)$$$: The y-intercept is where the line intersects (crosses) the y-axis. Mathematically, it's the value of $$$y$$$ when $$$x=0$$$. It is the point of the line on the vertical axis.

The slope-intercept form has a wide range of applications:

• Economics: Used to visualize cost functions, revenue functions, or any linear relation between variables.
• Physics: Helps to define relationships in linear motion or any scenario where a direct linear relationship is observed.
• Everyday Life: Can help to estimate budgets, predict outcomes, or calculate simple relations between two variables.
