Answer:
Step-by-step explanation:
It's an equation of a linear function in the slope-intercept form:
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
The domain of any linear function is the set of all real numbers.
The range of any linear function where m ≠ 0 is the set of all real number.
If m = 0, then the equation of a line is y = b. Then the range is {b}.
We have m = 1/4 ≠ 0. Therefore the range is the set of any real numbers.
Y1=2/3x , Y2=2/3x-2
those are the graph of the functions
