The endpoints of a side of rectangle ABCD in the coordinate plane are at A (3,9) and B(5, 1). Find the equation of the line that contains the given segment.
The line segment is CD and point C is at (9,2).
The equation is

y = - 4x + 38

Step-by-step explanation:

A(3, 9)

B(5, 1)

= = - 4

CD║AB

C(9, 2)

y - 2 = - 4(x - 9)

y = - 4x + 38

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
