If Omar needs to read 5 novels each month, then we can express it as 5M because M represents months, and this expression is equal to N because it represents the number of novels Omar needs to read.
Therefore, the equation that represents this situation is 5M = N.
Now, to graph the expression, we have to evaluate it when M = 1 and M = 2.
So, the ordered pairs are (1,5) and (2,10), let's graph them to then draw the line through those points.
