Writing Linear Equations from Graphs and Tables

The video tutorial explains the slope-intercept form of linear equations, represented as y = MX + B, where M is the slope and B is the y-intercept. It provides two examples to demonstrate how to find the slope and y-intercept from a graph and a table. The first example uses a graph to identify points and calculate the slope using rise over run, while the second example uses a table to determine the slope and y-intercept. The video concludes with a reminder to jot down any questions.

What is the general form of a linear equation in slope-intercept form?

• y = mx + b

• y = ax + b
