Engage in Activity 6.3 and learn how to use graphing software in graphing
linear equations.

Activity 6.3: Graphing linear equations using graphing tools

Write 5 linear equations of your choice and use a graphing software of your
choice to draw their graphs.

Exercise 6.6

1. Use a table of values to draw the graph of 2x + y –1 = 0 and hence
determine the x and y-intercepts.

2. Draw a graph for each of the following equations.

(a) x + 3y = 2 (e) 2 –9x = 3y

(b) 3x − 5y = 1 (f) y + 3x = 4
