Question

Help don't understand Slope and finding the distance

Answer 1

find the distance between j and k

Answer 2

1)Finding the slope.
This is done by y2-y1/x2-x1 where (x1,y1) and (x2,y2) are the 2 points of a line.
2) Distance
There is a formula called' DISTANCE FORMULA' which says
\[\sqrt{(x2-x1)^{2} + (y2-y1)^{2}}\]
Where (x1,y1) and (x2,y2) are the 2 points of the line between which you need the distance, it is measured usually in SQUARE.UNITS unless otherwise mentioned in question.

Answer 3

J(5,9) and K(-1,3)
\[\sqrt{(-1-5)^{2}+ (3-9)^{2}}\]
\[\sqrt{36 + 36}\]
\[\sqrt{72}\] which is \[6\sqrt{2}\]

Answer 4

I know that but that answers given was

A. 13.42
B. 8.49
C. 7.21
D. 12.65

Answer 5

Well 6 x 1.41= 8.48 which is closest to answer B.
