Is the graph linear or nonlinear?

• It's linear because it's a straight line.

• It's nonlinear because it goes both up and down.

• It's linear because it's a V shape.

• It's nonlinear because it's not a straight line.

• It's linear because the y-intercept is negative.

• It's nonlinear because the y-intercept is negative.

• It's linear because there are no exponents.

• It's linear because the slope is positive.
