Exercise 5 Page 91

Substitute some arbitrary values of x into the given equation.

Practice makes perfect
Let's start by isolating y in the given equation. 4x-3y = 12 ⇔ y = 4/3x - 4

To draw the graph of our equation, we will use a table of values. Substituting some arbitrary values of x into the given equation will give us the corresponding y-values.

x 4/3x - 4 y=4/3x - 4
- 3 4/3( - 3) - 4 - 8
0 4/3( 0) - 4 - 4
3 4/3( 3) - 4 0

Now let's plot these ( x, y) coordinate pairs and connect them with a straight line.
