Function : A function is a mapping in which every element in one set is mapped to exactly one element of a second set. Most often the mapping is described using a rule. For example the function $f(x)=x+1$ maps 2 to 3 and -1 to 0.
Graph : The graph of a function is the set of points $\{(x,f(x))\}$ that can be blotted in a coordinate system.
The above picture shows that graph of the function $f(x)=$_______.
Counterexample : A counterexample to a statement of the form 'all objects of type x have property y' is an object of type x that does not have property y. A counterexample to a statement shows that the statement is not true in general. For example the number 3 is a counterexample to the statement that all numbers are even.
Select all statements that are true about the function $y=mx+b$
