How do I graph f(x)=-3x+54?

Question

I don’t understand how I am supposed to graph this amount of numbers when my graph only goes so far. Normally y=mx+b is my formula. It is still the same formula technically, but I am just overall having a hard time with it.

Answer 1

f(x) = -3x + 54

You still use y = mx + b to graph the line.

Just let each mark on the y-axis = 9
