Answer:
Straight-line equations, or "linear" equations, graph as straight lines, and have simple variable expressions with no exponents on them. If you see an equation with only x and y – as opposed to, say x2 or sqrt(y) – then you're dealing with a straight-line equation.
There are different types of "standard" formats for straight lines; the particular "standard" format your book refers to may differ from that used in some other books. (There is, ironically, no standard definition of "standard form".)
Answer: Undefined
Step-by-step explanation:
slope is undefined
no y intercept
This line is vertical
Answer:
It is a linear function, because the line has no curve, and the line is constant
Step-by-step explanation:
In a non linear function there would be a curve in the line, in this line there is no curve so therefore it is linear function.
Answer:
To find the domain and range, we simply solve the equation y = f(x) to determine the values of the independent variable x and obtain the domain.
Step-by-step explanation:
To calculate the range of the function, we simply express x as x=g(y) and then find the domain of g(y).
