Question

find the distance between the point (-5,8) and (1,16)

whats the distance formula??

Answer 1

the distance formula is basically the pythagorean theorem

Answer 2

which is?...

Answer 3

the square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the lengths of its legs, or the length of the hypotenuse is equal to \[\sqrt{x^2+y^2}\]

Answer 4

\[\sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\]

Answer 5

to compute distances between points in the graph, you would apply that theorem.

\[Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\]

Answer 6

Where the coordinates of the 2 pts are (x1,y1) and (x2,y2)

Answer 7

thank youuuu

Answer 8

E=Dy/Dx
=(8-16)/(-5-1)
=-1.3333
