☪ 
- Slope ( m ) = -2
- Given point = ( - 1 , 8 )
☪ 
- Equation of a line in slope - intercept form ( i.e y = mx + c )
Let the point ( -1 , 8 ) be ( x₁ , y₁ )
☪ 

plug the known values :

Answer: 
Step-by-step explanation:

Answer: B) 2
Detailed Answer:
The degree of a polynomial is the highest power in the polynomial. Here the highest power is 2 hence the degree is 2. Polynomials with the degree 2 are also called quadratic polynomials.
Then the number must be between 18² = 324 and 19² = 361. But is that what you want to know?
