EXERCISE 23 B
1.Fill in the blanks:
(i) The graph of x=1 is a line parallel to the ____ axis
(ii) The graph of y=1 is a line parallel to the ____ axis
(iii) The equation ax+by+c=0 (where a and b are not both zero) is called a ___ equation.
(iv) The graph of 2x=1 is a line parallel to the ___ axis
2.Graph each of the following equations on a coordinate plane.
3.Complete the table of values for each equation and draw each line on a separate coordinate grid.
(i) x+y=5\rightarrow y=5-x
4.Draw a coordinate grid from -10 to 10 on both axes. Using table of values draw each line on the same grid.
