Step-by-step explanation:
Question 1
The point-slope formula for a straight line is
y – y₁ = m(x – x₁)
x₁ = 3; y₁ = -5; m = -4
Substitute the values
The diagram shows the graph of equation 1 (red) with slope -4 passing through (3,-5).
Question 2
x₁ = -1; y₁ = 8; m = 1
Substitute the values
The diagram shows the graph of equation 2 (green) with slope 1 passing through (-1,8).
Option a:
Option b:
Option c:
Explanation:
The highest degree of a polynomial is the largest exponent of that variable.
Now, we shall determine the polynomial with degree 3.
Option a:
From the expression , the highest degree of the polynomial is 3.
Hence, is a polynomial with a degree of 3.
Hence, Option a is the correct answer.
Option b:
From the expression , the highest degree of the polynomial is 3.
Hence, is a polynomial with a degree of 3.
Hence, Option b is the correct answer.
Option c:
From the expression , the highest degree of the polynomial is 3.
Hence, is a polynomial with a degree of 3.
Hence, Option c is the correct answer.
Option d:
From the expression , the highest degree of the polynomial is 1.
Hence, is a polynomial with degree 1.
Hence, Option d is not the correct answer.
