(5x+6xy-4)-(-6x+7xy+2)
5x + 6xy - 4 + 6x - 7xy -2
11x - xy - 6
Answer: The first equation is an equation of a parabola. The second equation is an equation of a line.
Explanation:
The first equation is,
In this equation the degree of y is 1 and the degree of x is 2. The degree of both variables are not same. Since the coefficients of y and higher degree of x is positive, therefore it is a graph of an upward parabola.
The second equation is,
In this equation the degree of x is 1 and the degree of y is 1. The degree of both variables are same. Since both variables have same degree which is 1, therefore it is linear equation and it forms a line.
Therefore, the first equation is an equation of a parabola. The second equation is an equation of a line.
