Rational number is something that does not have a decimal number going to infinity or something that can be written as a fraction
21.192 can be written as 21 192/1000 so yes its rational
i.e. √2 goes on forever and cannot be written as a fraction. so no it is not rational. it is irrational just like π.
Hope this helps :P
Answer:
-3
Step-by-step explanation:
The wording is basically saying the y-intercept so when it talks about initial value thats what its talking about. Its negative because it's on the further down side of the y axis. Y-intercept is where the line of a graph crosses the y axis like shown in the picture it is at -3.
Answer:

so y = 3x - 3
since 3x + 6 is on the bottom,

so this means it should be the graph of y = 3x - 3, but with a hole at (-2, -9)
