Find the rate of change from the table.

3/2

Step-by-step explanation: because you write in order you x and y and you need to remember that it is y/x all the time when doing rate of change. when you have wrote the down in oder look at them what do you notice in your y? well it is going up by three -10 20 50 and 80. What do you see in your x? well it is going up by 2 0 2 4 6.
