Step-by-step explanation:

Step 1:

y = mx + b Slope Intercept Form

Step 2:

y = -x + b Input Slope

Step 3:

7 = - 1 ( 1 ) + b Input x and y

Step 4:

7 = - 1 + b Multiply

Step 5:

b = 8 Add 1 on both sides

1.Which expressions are polynomials? Select each correct answer. Pick more then one.

madreJ [45]

If all the power of the variables are greater than or equal to zero, then the expression is a valid polynomial.

So,

$7x^{7}-x-5$

$35x^{2}$

$\frac{x}{5}+2$

are polynomials.

$x^{2} -x\sqrt{2}$

2 + s

$4x^{2} +y$

are all polynomials.

If the degree of the polynomial is 3, then it is a cubic polynomial. If the number of terms of a polynomial is 3, then it is a trinomial.

Hence, $-5x^{3}-4x+1$ is a cubic trinomial.

The highest power is the degree.

Hence, degree of the polynomial is 2 + 4 = 6.
