• #### How Do You Determine if a Graph Represents a Linear, Exponential, or Quadratic Function?

Graphs come in all sorts of shapes and sizes. In algebra, there are 3 basic types of graphs you'll see most often: linear, quadratic, and exponential. Check out this tutorial and learn how to determine is a graph represents a linear, quadratic, or exponential function!

• #### What is a Regression Line?

Scatterplots of data on the coordinate plane sometimes reveal patterns. If the data appears to be roughly linear. A line drawn through the middle of the data, or regression line, can be used to make predictions about the data. Check out the video to learn more about regression lines!

• #### What is Linear Regression?

Sometimes Real-world data follows a linear pattern. A linear regression is a the equation for a linear function that most closely follows the given data. Watch the tutorial to learn more about modeling data with linear functions.

• #### How Do You Write and Use a Prediction Equation?

Scatter plots are a great way to see data visually. They can also help you predict values! Follow along as this tutorial shows you how to draw a line of fit on a scatter plot and find the equation of that line in order to make a prediction based on the data already given!
