4.11.1 Graphing Linear Functions

4.11.1 • Graphing Linear Functions

Warm Up

1.

Use the Desmos graphing tool or technology outside the course. Graph the following lines given in slope-intercept form.

  • y=3x+4y=3x+4
  • y=3x−2y=3x−2
Access multimedia content
2.

What is the relationship between the two lines you graphed in question 1?

3.

When you examine the equations of the lines, what do you notice is the same about the equations?

4.

When you examine the equations of the lines, what do you notice is different about the equations?

5.

When you examine the graph of the lines, how many vertical spaces are between the two lines?

6.

Use the graphing tool above or technology outside the course, on your coordinate grid, use the slope and yy-intercept of each equation to graph each equation. Use a different color for each equation.

  • y=3x−2y=3x−2
  • y=−13x−3y=−13x−3
Access multimedia content
7.

When you examine the graph of the lines in question 6, explain if the lines appear to be perpendicular.
