Answer:
It's linear
Step-by-step explanation:
Linear equations have no exponents higher than a 1, which is the case for this equation cause if there's no exponent it's cause it's just a 1. Non-linear has a exponent higher than a 1, ex. 
Answer:
Antoinette's error
Option A) She distributed incorrectly.
Step-by-step explanation:
We are given the following information in the question:
Antoinette solves the linear equation

Antoinette made mistake in step 1 that is she did not distributed correctly.
If she would have distributed correctly, then she would have got the following solution:

Substituting x = -1 in the given equation, we gwt:

Antoinette's error
Option A) She distributed incorrectly.
The geometric term described as an infinite set of points that has
length but not width is called a line. It has a negligible with and depth. In
geometry, a line located in the plane is defined as the set of points whose
coordinates satisfy a given linear equation. A line segment however is a line
connected by two dots far apart from each other and then connected. For example
is the equation y=mx+b. This is a slope intercept form which is a linear
equation.
