Answer:
Yes. Every unique input has a unique output.
Step-by-step explanation:
Since every input has a different output, therefore it's a function. It's not a function when the input have more than 1 output. When graphing, make sure you take the vertical line test to see whether or not the graph is a function.
Answer: -7
Step-by-step explanation: .........................
y+1=9(x+3)
Since the equation for point slope form is y-y₁=m(x-x₁)
enter the given points (-3,-1)
y-(-1)=9(x-(-3))
y+1=9(x+3) <-- point slope form
