To graph the linear equation, follow the steps below.
Step 01: Choose one value for x and find its corresponding y-value.
Choosing x = 0:

Dividing both sides by -2:

So, the linear equation has the point (0, -6).
Step 02: Choose another x value and substitute it in the equation.
Let's choose x = 2.

Subtracting 12 from both sides:

So, the equation has the point (2, 0).
Step 03:
Plot the point and connect them.
