Question

Edgar started with 2 poems in his journal. Then he started writing 3 poems each day. Which of the following graphs represents Edgar's poem writing

Answer 1

Answer:  

Let x represents the number of the days, and y represents total number of the poem.

According to the question,

Edgar started with 2 poems in his journal. Then he started writing 3 poems each day.

Thus, the line that describes the above situation is,

y = 2 + 3 x

The x -intercept of the line is $(-\frac{2}{3} , 0)$ or (-0.667 , 0)

And, the y-intercept of the line is (0,2)

Also, if x = 1 y = 5

if x = 2 y = 8

If x = -1 y = - 1

And, if x = - 2 , y = -4

Thus, the points by which the line will pass are,

(1,5), (2,8) , (-1,-1) and (-2,-4)

Therefore, with the help of the above information we can plot the graph of the line. ( shown below)
