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!
