Answer 1

Draw a number line. Plot the points 4 and -7 on it. How many spaces are between the two numbers?

Answer 2

21 (I messed up it isn't 7, it's 17)

Answer 3

oh so X = 4 and Y = -17 ?

Answer 4

Yes, sorry

Answer 5

yes, the distance between the two values is 21 units

Answer 6

How about 2. and 4.?

Answer 7

in #2, the two numbers are positive, so you can subtract

23 - 8 = 15

Answer 8

Oh, makes sense thanks

Answer 9

you can also subtract in #1

x - y = 4 - (-17) = 4 + 17 = 21

Answer 10

Oh thanks

Answer 11
