Question

Y = 2x + 9 + xis this equation linear or nonlinear?​

Answer 1

$\text{This would be a linear line}\\\\\text{Due to the fact that when you solve the equation, you should get y = 3x + 9}\\\\\text{The slope in constant. The slope here would be 3}\\\\\text{Since the line is always at a constant rate of change, this would make}\\\text{the line linear}$

Answer 2

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 .
