Completing Tables using the given equation.Graphing the table of valuesTRANSCRIPT
A REMINDER OF…
REMEMBER???
DO NOW…
TODAY Learning Target:!• I can graph an increasing or decreasing linear relationship by creating a table and plotting the
points."• I can recognize when a linear relationships is a horizontal line or a vertical line AND I can graph
horizontal and vertical lines from a given equation."• I can use my graphing calculator to check my graphs and tables."!Agenda:!• Do Now"• Recognizing Linear Relationships"• Activity 1: Graphing a linear relationship from a table "• Activity 2: Using your graphing calculator to check the graph of a line or the table of a line"• Graphing Horizontal and Vertical Lines"• Summarize""HW: ALG. 1 – LESSON 2.1 D ON ASSISTMENTS!PROBLEM # - 1,2, 10 – 26 (EVEN), 25, 27, 28 – 32 "ON P. 46 – 47 IN YOUR TEXTBOOK."
USING THE GRAPHING CALCULATOR
I will table and graph the equation y = 2x + 5""1) Using y= button"2) Using the viewing window"3) Pressing GRAPH"4) Changing the viewing window"
GRAPHING ON PAPER, CHECKING USING CALCULATOR
GRAPHING HORIZONTAL AND VERTICAL LINES
PRACTICE …
SUMMARIZE:
Explain how you know if an equation is linear.
FROM A TABLE (NUMBERS)
DO NOW: RECOGNIZE A LINEAR RELATIONSHIP FROM AN EQUATION
NEXT: RECOGNIZE A LINEAR RELATIONSHIP FROM A GRAPH
FROM A STORY
SUMMARY: TO GRAPH A LINEAR RELATIONSHIP:
• You must be able to use the Order of Operations correctly to evaluate a rule."
• You must be able to plot points correctly on the coordinate plane. Remember x, then y."
• A (unique) straight line may be drawn from any point to any other point. "
• Every straight line can be extended indefinitely."• Even though you only need two points to draw the unique line,
a line is comprised of an infinite number of points that are ALL solutions to the equation of the line."
