Ответ:
The correct statement is (b) which is f(x) has no
term
Explanation:
The graph of a linear equation is a straight line. The general form of a linear equation is
ax + by + c = 0
Here, the coefficients a and b can't be zero simultaneously.
The term 'c' is a constant and can be zero.
We can see that the exponent on each variable x and y is 1. So, if the exponent in any variable is not 1 then that will not be a linear equation.
Other than this, the coefficients a and b can be zero at a time.
If a = 0 , then the x term will be zero.If b = 0, then the y term will be zero.Therefore, on the basis of these facts, we can conclude that the necessary condition for an equation is to be a linear equation is " it should not have any
term"
If we have
in our equation then it will be a quadratic equation.
Therefore, option b is correct.
Further Explanation:
Any function which is in the form ax+by+c=0 is called a linear function.
Linear function always represents a straight line.
The slope intercept form of a line is
. Here, m is the slope and b is the y-intercept.
The formula for slope of a straight is given by
