Can someone tell me if my answer is correct for this one. i need to know if the floor is positive, negative, zero or undefined. i say it's undefined

If you mean the y coordinate of that line, then it would be negative because it goes through -4 on the y axis.

the final function for the graph becomes x-2=-1. before graphing you solve the equation, where x=1. then graph accordingly.   ( on the x-axis, 1 on the line will possess a vertical line.)

step-by-step explanation:

if x = 2 you have to find x to finish the problem
