Question 80171
Yes it is because the power of the variables ( x and y ) is one. If you had an equation which contained {{{x^2}}} or {{{y^3}}} then the equation would not be linear, because the power of the variables is higher than 1 and if you were to graph it, your graph would not look like a line. The best way to differentiate is the formula for linear equations, which is {{{y=m*x+b}}} ie {{{y=2*x+3}}}. If your equation looks like the above then you have a lindear equation.

Good Luck!
