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:

Answer:
The points are sqrt(164) or 2sqrt(41) units apart.
Explanation:
You didn't provide the options in your question. But to find the distance, you need to use the distance formula.
d=sqrt((y2-y1)^2 + (x2-x1)^2)
d is the distance, and (x1, y1) and (x2, y2) are the points.
Use point J (-4,-6) for (x1,y1) and point K (4,4) for (x2, y2).
d=sqrt((4-(-6))^2 + (4-(-4))^2)
=sqrt(10^2 + 8^2)
=sqrt(100+64)
=sqrt(164)=2sqrt(41)
You can compare this to the answer options and find the closest. Hope I could help! :)
