We have given two function of variable <em>x </em>and <em>y</em>


<h3>Polynomial</h3>
An expression of two or more algebraic terms, which is the sum or difference of the several terms with having different power of the only variable.
Now we have to subtract the two equations to find the difference,

Multiply the sign into the bracket to open the bracket and further solution,

Arrange the similar terms in the same groups,


Hence, the difference between the given polynomials is

Answer:
y = x - 4
Step-by-step explanation:
equation of a line can be expressed as
(x - x1)/(x2 - x1) = (y - y1)/(y2 - y1)
(x - 5)/(10 - 5) = (y - 2)/(-3 - 2)
cross multiplying,
-5(x - 5) = 5(y - 2)
clearing the parentheses
-5x + 10 = 5y - 10
hence,
5y = 5x - 20
y = x - 4
