You can determine whether a graph is a function or not if it’s points create a straight , consistent line. there will be no curves or intersecting lines on the graph.
The correct answer should be 4. 2 times 0.3 is 0.6. 3.4 plus 0.6 equals 4. ;)
3y-3y+-4=9y-3y-8
-4=6y-8
-4+8=6y-8+8
4=6y
y=4/6
y=2/3 (66.6%)
