Is the sum of two monomials always a monomial? Is their product always a monomial?
Ivan

Sum of two monomials is not necessarily always a monomial.

For example:

Suppose we have two monomials as 2x and 5x.

Adding 2x+5x , we get 7x.

So if two monomials are both like terms then their sum will be a monomial.

Suppose we have two monomials as 3y and 4x

Now these are both monomials but unlike, so we cannot add them together and sum would be 3y + 4x , which is a binomial.

So if we have like terms then the sum is monomial but if we have unlike terms sum is binomial.

Product of monomials:

suppose we have 2x and 5y,

Product : 2x*5y = 10xy ( which is a monomial)

So yes product of two monomials is always a monomial.

Use the slope formula to find the slope of the line that passes through the points (4, -1) and (3, -1) *
GenaCL600 [577]

Answer:

slope = 0

Step-by-step explanation:

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (4, - 1 ) and (x₂, y₂ ) = (3, - 1 )

m = \frac{-1-(-1)}{3-4} = \frac{-1+1}{-1} = \frac{0}{-1} = 0
