Identify the unit rate in the graph. A) $5 B) $10 C) $15 D) $20
The unit rate would be earnings per hour ($/hr). The x value will always be in the denominator part since it is the independent variable and the y value will always be in the numerator since it is dependent.
Easy, write the coordinates out in pairs: x= hours y= earnings (1,10) (2,20) (3,30) (4,40) (5,50) Now it makes it much easier to see the increase, After 1 hour of working she has made $10 After 2 hours of working she has made $20 After 3 hours of working she has made $30 And so on, that being said it's easily seen that she is getting paid $10 Thus the unit rate is $10.
