Step-by-step explanation:

a) The term "rate of change" refers to "slope" or "unit rate" on a graph. In a linear equation, it is the coefficient of the variable.

On the graph, it can be found by counting the vertical units that correspond to each horizontal unit. On this graph, a horizontal increase of 1 grid square (5 subscriptions) causes an increase of 1 grid square ($5) in earnings. The rate of change is ...

  m = rise/run = $5/(5 subscriptions) = $1 per subscription

__

c) As indicated above, this will translate to the coefficient of the variable in the equation.

  E = n + 45
