Plot Straight Line Graphs - Part 2

The video tutorial guides students on how to plot straight lines on a graph using a table of values. It emphasizes completing the table, plotting points, and connecting them with a line. The tutorial also discusses handling fractions and using different X values, including negative ones, to ensure accurate plotting. By the end, students should be able to plot any straight line on a graph by choosing appropriate X values.

What is the first step in plotting a straight line on a graph?

• Complete the table of values

• Draw the axes

• Choose random points

• Label the graph

Why should fractions be avoided when plotting points on a graph?

• They are too complex to calculate

• They cannot be plotted accurately

• They are not allowed in graph plotting

• They make the graph look messy

What should you do if the graph is not large enough to plot a coordinate?

• Ignore the coordinate

• Use a different graph

• Plot it approximately

• Change the scale of the graph

How many sets of coordinates are needed to accurately plot a straight line?

• Four

• Three

• Two

• One

What might you need to do if the initial X values do not provide enough points?

• Increase the number of Y values

• Try different or negative X values

• Change the graph paper

• Use only positive X values
