Answer:
length of its each side is 786 cm
Step-by-step explanation:
l² = 617796cm²
l = √617796
l = 786cm
K is the slope of the line formed by connecting the points.
Use slope formula:

where the 2 points are the end points of the line (First and last going Left to right)

Substitute into slope formula

You can check if this is correct by going back to graph and going "up 7" and "over 2" to get from one point to the next.
Answer:
B
Step-by-step explanation:
When looking at the number line, we can see the distance between A and B is one unit
A |-2| + |-1| = 2+1 =3 That is not 1 unit
B 2-1 =1 that is 1 unit
C -2 + -1 = -3 that is not 1 unit
D |-1| - (-2) = 1 + 2 =3 that is not 1 unit
Even though it says all expressions, there is only 1 that shows a distance of 1 unit
