Write the equation of the line in
Brut [27]

Answer:

y - 3= 2(x - 0)  

Step-by-step explanation:

hello :

note 1 :

the point-slope formula is :

y - y_1 = m(x - x_1)   the point is A(x_1  , y_1 )  , m :  the slope

note 2 :

the slope is :   m = (y_2 - y_1)/(x_2 -x_1)  when given two points  :

A(x_1  , y_1 )  and  B(x_2  , y_2 )

in this exercice :  x_1 =0      y_1 =3            x_2 =1      y_2 =1

calculate now   m = (1 - 3)/(1 -0) =-2

an equation  in point-slope form is : y - y_1 = m(x - x_1)  

y - 3= 2(x - 0)

What is the probability that a point chosen at random in the triangle is also in the blue square?
matrenka [14]

The <u>probability</u> that a point <u>chosen at random</u> in the triangle is also in the blue square can be calculated using <u>geometrical definition of the probability</u>:

Pr=\dfrac{\text{desired area}}{\text{total area}}.

1. Find the total area of the triangle:

A_{total}=\dfrac{1}{2}\cdot 6\cdot 9=27\ in^2.

2. Find the desired area of the square:

A_{desired}=3\cdot 3=9\ in^2.

Then the probability is

Pr=\dfrac{9}{27}=\dfrac{1}{3}.

Answer: correct choice is B
