Key concepts
3 concepts
- 1
To graph a linear equation using a table of values, you can select any x value and substitute it into the equation to find the corresponding y value.
- 2
It is best practice to find at least three points when graphing a line; if the points don't form a line, you know you've made an error.
- 3
After plotting the points from your table of values, draw a line that passes through all the points to represent the graph of the linear equation.

Practice
12 questions
What is the minimum number of points you should find when graphing a line using a table of values, and why?
Suppose you are graphing the equation y = 3x - 2 using a table of values. If you choose x = 2, what is the corresponding y-value?

Quick comprehension check
“Create a table of values for the equation y = 3x - 2 using the x-values -2, -1, 0, 1, and 2. Then, list the coordinates of the points that would be on the line.”
