Describe what the graph of interval [-4,10] looks like.

horizontal line on x axis between those numbers.

Thats all it is? How did you come to this conclusion? Just trying to understand algebra after being out of school 25 years, thank you for your help.

To describe the graph of the interval [-4, 10], we imagine a number line. The closed bracket "[" at -4 signifies that -4 is included in the interval, meaning it is part of the graph. The closed bracket "]" at 10 also includes 10 in the interval, so it is part of the graph as well.

Therefore, the graph starts at -4 and goes all the way to 10, including both -4 and 10. It consists of all the real numbers between -4 and 10, including -4 and 10 themselves. This can be visualized as a solid line segment on the number line, with a closed dot at -4 on the left side and a closed dot at 10 on the right side.
