Answer:
The equation that models the relationships between , the number of hours Mark reads, and ,
the number of pages of the book he reads is:
Step-by-step explanation:
Given:
Mark reads 42 pages every hour.
The number of hours is given by =
The number of pages is given by =
The equation can be modeled as:
where represents rate of change and
represents the y-intercept or the initial value.
Rate of change =
The initial value as Mark starts reading from 0.
So, the equation is:
