Evaluating Linear Functions and Graphs

The video tutorial explains how to graph a linear equation by filling out a table of values. It begins with an introduction to graphing points and tables, then details the process of choosing x-values, calculating corresponding y-values, and completing the table. Finally, it demonstrates how to plot these points on a graph to visualize the linear equation as a straight line.

What is the first step in graphing a linear equation?

• Drawing a straight line

• Calculating the slope

• Plotting random points on a graph

• Filling out a table of values

What is the general form of a linear equation?

• y = mx + b

• y = ax^2 + bx + c

• y = ax^3 + bx^2 + cx + d

• y = a/x

What do you need to do after filling out a table of values?

• Find the y-intercept

• Calculate the slope

• Draw a parabola

• Graph the points

Which equation is used in the example to fill out the table of values?
