Question

A line 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.

Answer 1

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.

Answer 2

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