Concept

Objective: Students will complete function tables and graph linear functions from equations.

Estimated Time: 12 minutes

Standards:
HSA-CED.A.2HSF-IF.C.7

A linear function has constant rate of change. For y = mx + b, each +1 in x changes y by m, and b is the y-intercept.

Try it

Given y = 2x - 3, complete values for x = -1, 0, 2 and graph the three points.

๐Ÿ“ˆ Coordinate Grapher

Graph your completed table and compare to the equation.

y = y = 1x

Concept Check

If y = 3x + 1, what is y when x = 2?

Concept Check

Which point is on y = 2x - 3?

Common Misconception
Always verify your result in context instead of trusting a first pass.

Graphing from an equation

These steps are out of order โ€” can you fix them?

1.Find two or more points
2.Substitute x-values into the equation
3.Plot points and draw the line
4.Interpret slope/intercept

Short Answer

Why is a table useful before graphing a line?
