Help me please. I need to find the length of jk and jp and compare the lengths

Jk is 4/5 and jp is 5/1

To find the lengths of two lines of a graph, you use the distance formula:
d = √(x2-x1)^2 + (y2-y1)^2 where d is distance and (x1, y1) and (x2, y2) are coordinates of the beginning and end of a line segment.

To find the distance of segment JL, plug the coordinates (1, -1) and (2, 4) into the distance formula:
d = √(2-1)^2 +(4+1)^2
d = √1+25
d = √26 = 5.099 units

To find the distance of segment JK, plug the coordinates (2,4) and (7,8) into the distance formula.
d = √(7-2)^2+(8-4)^2
d = √25+16
d = √41 = 6.403 units

The length of segment JK is 6.403 units. The links of segment JL is 5.099 units. Segment JK is longer than segment JL.
