The slope is the change in Y over the change in X.
Find 2 points on the line that cross X and Y that are easy to tell what numbers they are.
First point( 0,-4)
Second point (8,0)
The change in Y would be 0 - -4 = 0+4 = 4
The change in X would be 8 -0 = 8
The slope is 4 / 8 which reduces to 1/2

Step-by-step explanation:
In mathematics, the domain of definition (or simply the domain) of a function is the set of "input" or argument values for which the function is defined. That is, the function provides an "output" or value for each member of the domain. Conversely, the set of values the function takes on as output is termed the image of the function, which is sometimes also referred to as the range of the function.
