1) 12
2) -4
I hope this was correct？
A proportional relationship runs through the origin and is a straight line. If you have a table, use the points to determine the slope. Is there one slope? If so, it is a proportion. If there isn't, it is not a proportional relationship (which is what you're looking for). Do you have a graphing calculator on hand? Those are extremely useful when you have an equation. Graph the equation and look at the image. Is it NOT straight? Does it NOT pass through the origin? This is how to find whether an equation is proportional or not.
Answer:
what is x equal to
Step-by-step explanation:
for example x= 3
and then you put
f(3)= slope + y - intercept
see how i changed f(x) to f(3) becuase the x was 3 and i put it there
