Answer:
y = - 3x - 2
Step-by-step explanation:
The function is linear and can be expressed in slope- intercept form
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (- 2, 4) and (x₂, y₂ ) = (- 1, 1) ← 2 ordered pairs from the table
m = =
=
= - 3 , then
y = - 3x + c
To find c substitute any ordered pair into the equation
using (0, - 2 ) , then
- 2 = - 3(0) + c = 0 + c ⇒ c = - 2
y = - 3x - 2 ← function rule
Answer: B) It represents the product of two irrational numbers and is equivalent to an irrational number.
Step-by-step explanation:
1. By a definition an irrational number cannot be written as a simple fraction.
2. Keeping this information on mind:
(Cannot be written as a simple fraction. It is an irrational number).
(Cannot be written as a simple fraction. It is an irrational number).
3. When you multiply this irrational number, you obtain:
4. is an irrational number.
5. Therefore, the answer is the option B,
