Aline segment is drawn from (1, 3) to (8, 3) on a coordinate grid. which answer explains one way that the length of this line segment can be determined? a. subtract 8 – 1. b. subtract 8 – 3. c. add 1 + 3. d. add 1 + 8.

Add 1+8 because those are your 2 x values to get the length of the segment.

While I don't want to give away the answer,  will help you eliminate a few answers.

First off, we'll look at B. This option states that you'd subtract the y coordinate from the first point from the x coordinate fro the second point. Does it make sense to subtract x-y?

Next, we can look at A. This states subtracting the x coordinate from the first point from the x coordinate of the second point. Does x-x make sense?

And finally, I'll explain D. This states adding the x coordinate from the first point from the x coordinate of the second point. Adding x+x? I don't think that makes sense.

I'd suggest choosing A. However, it is up to you.
