Describe several real world situations can be modeled by equations of the form Y equals MX plus be or Y equals MX explain how the latter equation represents a proportional relationship

The linear equation represents y = mx + b describes several real world situations such as

Step-by-step explanation:

Linear equations  y = mx + b.  

m is your rate of change.

b is your constant. This is the initial value of y. The value of y when x is 0.

Finally, y is the thing that depends on x.

Oh right, examples:  

total cost = 25(cartridges I buy) + 100 or y = 25x + 100

amount left on card = -$1(songs bought) + 100 or y = -x +100

its 69.420
