Answer:
x = 1.5
Step-by-step explanation:
We need a value of x that would result in 2x+9 = 12
2x+9 = 12
2x = 12 - 9
2x = 3
x = 3/2 or 1.5
====
CHECK
Does 2x+9 = 12 when x = 1.5?
2x+9 = 12
2(1.5)+9 = 12
3 + 9 = 12 YES
So for 9, to graph all you need to do is start at the origin (0,0) and go up 4 and over (right) 1.
