Converting Non-Proportional Tables to Equations

The video tutorial explains how to find equations for non-proportional tables using the formula y = mx + b. It covers calculating the slope and y-intercept, even when x=0 is not present, through algebraic methods. The tutorial includes multiple examples to illustrate the process and verify the correctness of the equations.

What formula is used to find the equation of non-proportional tables?

• y = mx + b

• y = m + b

• y = mx

• y = x + b
