What is the distance between A and B? Round your answer to the nearest hundredth.

Reika [66]

An extension of the Pythagorean Theorem results in what is the so-called "distance formula".

d^2=(x2-x1)^2+(y2-y1)^2, in this case you have points (-2,4) and (2,0) so:

d^2=(2--2)^2+(0-4)^2

d^2=4^2+(-4)^2

d^2=16+16

d^2=2*16

d=√32 units

d=√(2*16)

d=4√2 units

d≈5.66 units (to nearest hundredth of a unit)

If (k,6k) and (3k,10k) are two points on the graph of a line and K is not equal to 0, what is the slope of the line?

Nataliya [291]

Answer:

Step-by-step explanation:

slope = y2-y1/x2-x1

Given the coordinates (k,6k) and (3k,10k)

x1 = k

y1 = 6k

x2 = 3k

y2 = 10k

Substitute

slope = 10k-6k/3k-k

slopw = 4k/2k

slope = 4/2

slope = 2

Hence the slope of the line is 2
