Is the following table proportional? Why? What is the equation of this table?
X Y
4 10
5 12.5
10 25
13 32.5
Yes, the table is proportional because it will end up having (0, 0) which if we were to graph it would go through the origin. It is also has a constant slope.
y= 2.5x or y=5/2x
Is the graph proportional or not? Why?
Non-proportional. It's not going through the origin (0,0)
Is the following table proportional? Why?
X Y
2 12
5 24
12 52
No, The table is non-proportional because it does not go through the origin.
Is the following graph proportional or not? Why?
No, it is non proportional. There is an adjustment being made which gives the graph a y-intercept.
Is the following ratio table proportional?
No, There is no constant change.
Is this a proportional relationship? Explain.
yes, because it is a straight line and starts at (0,0)

Passes through the origin.
What is the equation of the following table? Also, is it proportional or non proportional?
y= x
It is proportional because it goes through the origin and has a constant rate of change.
Given this table, what equation represents this situation?
y = 10x + 11
