Substitute some arbitrary values of x into the given equation.
Practice makes perfect
Let's start by isolating y in the given equation.
3y = 6 + 9x ⇔ y = 3x + 2
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
3x + 2
y = 3x + 2
- 1
3( - 1) + 2
- 1
0
3( 0) + 2
2
1
3( 1) + 2
5
Now let's plot these ( x, y) coordinate pairs and connect them with a straight line.
