Answer:
Unit rate = 0.6
y = 0.6x
x= 24
Explanation:
I cannot see the headings to the table, but on examining the questions, the first column contains the values for variable x and the second column the values for variable y
Unit Rate
Unit rate = increase in y for a unit increase in x
We see that the rate is constant for every unit increase in x and is = 0.6
Unit rate = 0.6
Equation
The equation therefore is y = 0.6x
Value of x when y = 14.4
When y = 14.4, plugging into the equation gives:
14.4 = 0.6x
or
0.6x = 14.4 by switching sides - no effect on equation
Divide both sides by 0.6
0.6x/0.6 = 14.4/0.6
x= 24
