Answer:
y = -2x + 5
Step-by-step explanation:
y=-3
Slope of this line m₁ = 1/2
Slope of the line perpendicular to this line = m₂
m₁ *m₂ = -1
m₂ = -1 *2/1 = -2
Slope = -2; (1,3)
y- y₁ = m(x-x₁)
y - 3 = -2(x - 1)
y - 3 = -2x + 2
y = -2x +2 +3
y = -2x + 5
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.
