Question

Construct a table of solutions and then graph the equation.

y = 7/ 8 x − 6

Answer 1

Before graphing the given equation we have to see that if they are any excluded values that is where the function is not defined then we have to find those values.

For the above equation we find the excluded value by setting the denominator to zero that is

Now we can see that the graph is not continuous or smooth at the point . This value is usually indicated as a Hole ( ) in the graph.

Now we can find some other points on the graph for plotting in the following table.

	-2	-1	0	1	2	6
	-0.318	-0.5	1.16	3.5	0.7	0.16

In the above graph the green colour Hole shows the point at which the equation is not defined.
