Answer:
Let x represents the number of the days, and y represents total number of the poem.
Since, Alex started with 3 poems in his journal. Then he started writing 2 poems each day.
Therefore, the line that describes the above situation is,
y = 3 + 2 x
The x -intercept of the line is (-1.5,0)
And, the y-intercept of the line is (0,3)
Also, if x = 1 y = 5
if x = 2 y = 7
If x = 4 y = 11
Thus, the points of the line are,
(1,5), (2,7) , and (4,11)
With the help of the above information we can plot the graph of the situation. ( shown below)
