The statement which is true for the function having slope is that the function is linear.
What is function?
Function is like a defined relationship between two or more variables expressed in equal to form. In a function each value of x must has a corresponding y value. The value which is entered in the function is known as domain and the value which comes out after is codomain of the function.
How to find function?
We have been given that slope of function is -3.
1) The function is linear because slope is in single number.
2) We cannot say that the equation is y=-3x because it depends on other points also. Suppose the point at which the line passes is (1,2)
y-2=-3(x-1)
y-2=-3x+3
y=-3x+3+2
y=-3x+5
So this statement is wrong,
3) Same in statement third , we cannot say that the point (2,-6) lie on line.
4) It is wrong because in the given option slope is -1/3.
Hence the correct statement is that the function is linear.
