Hours worked : 2 | 4 | 5 | 8 | Amount paid : 30.40 | 60.80 | 76 | 121.60 |

OpenStudy (skullpatrol):

Any ideas?

OpenStudy (tylerd):

the slope of the equations is the rate

OpenStudy (tylerd):

so you have to write an equation for hours worked and amount paid

OpenStudy (anonymous):

okay

OpenStudy (skullpatrol):

Do you know the definition of a rate?

OpenStudy (tylerd):

30.4=m(2)

OpenStudy (skullpatrol):

A rate is a ratio that compares the amounts of two different kinds of measurements :-)

OpenStudy (anonymous):

a rate is well yeah thanx :)

OpenStudy (skullpatrol):

Calculate the rate from the given data.

OpenStudy (anonymous):

okay

OpenStudy (skullpatrol):

Rate = amount paid / hours worked

OpenStudy (anonymous):

Alright

OpenStudy (skullpatrol):

Can you do that?

OpenStudy (skullpatrol):

Find the slope.

OpenStudy (tylerd):

it follows the general form y=mx or amount paid = rate x hours worked

OpenStudy (anonymous):

i can try

OpenStudy (tylerd):

do or do not, there is no try.

OpenStudy (skullpatrol):

(Change in y)/(change in x) = rate

OpenStudy (anonymous):

okay sorry and ok

OpenStudy (skullpatrol):

Without effort there is no learning and understanding

OpenStudy (skullpatrol):

Use the given data.
