Linear Graphs Quiz

What is the first step in plotting a linear graph on a coordinate plane?

• Label the x and y axes

• Calculate the slope of the line

• Determine the scale for the x and y axes

• Draw the line connecting the points

How do you find the slope of a linear graph?

• By finding the area under the graph

• By counting the number of points on the graph

• By using the formula: (change in y) / (change in x)

• By using the formula: (change in x) / (change in y)
