Answer:
4
Step-by-step explanation:
go on the x-axis where you see 8
go up until you get to the line
go toward the y-axis to the left and read ( it said 4)
Subtract 3 from both sides
(z = -9 - 3)
Simplify -9 - 3 to -12
z = -12
3 + -12 = -9 so this is true.
The answer to number 5 would be negative 8 and 1/12.
Hope this helps!!
