Answer:
Linear
Step-by-step explanation:
Add 2 x and x . y = 3 x + 9 A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 or 1 for each of its variables. In this case, the degree of variable y is 1 and the degree of variable x is 1 .
[tex]\text{This would be a linear line}\\\\\text{Due to the fact that when you solve the equation, you should get y = 3x + 9}\\\\\text{The slope in constant. The slope here would be 3}\\\\\text{Since the line is always at a constant rate of change, this would make}\\\text{the line linear}[/tex]
