Y=5/4x-4
5/4 is the slope but to pass through the point it needs to cross the y axis at -4

Does this graph represent a function? What is the domain and range of the graph?
1 answer:
Answer:
Yes; domain: all real numbers; range: y 0
Step-by-step explanation:
1. Use the vertical line test to see if it is a function.
2. Figure out what the lowest and highest point x can be. In this case x can be any number
3. Figure out what the lowest and highest point of y can be. In this case y is not negative, the lowest it can be is 0. So y 0
*Note: Domain are the x values & Range are the y values
