Exercise 2 Page 187

The graph of y=b is a horizontal line passing through (0,b).

Practice makes perfect

We want to draw the graph of the given linear equation.

y= - 2 To do so, recall that the graph of y= b is a horizontal line passing through (0, b). In our equation, we see that b= - 2. Therefore, its graph is a horizontal line that passes through (0, - 2).
