Module 4, Part 2 Solutions Video. Question 20

GRE Quant Problem Solving

Hello,

In the solutions video for Algebra Quiz #2 in the “I’m Overwhelmed” study plan, Greg says that ∣x∣+1=y is not a linear equation because x in the absolute value does not have an exponent. But, what about the y value?

Thanks

The reason it’s not linear is because of the absolute value around x, which changes the shape of the graph. Y is fine on its own. It’s how x is used that makes it non-linear.

I hope this is what you’re looking for. If not, feel free to rephrase the question!
