Question

Billy started with 2 poems in his journal. Then he started writing 4 poems each day. Which of the following graph represents Billy's poem writing?

Answer 1

The equation would be y = 4x + 2 so just look with a graph that has a y-intercept of two, as well as moves up four and up 1 each time.

x / y
0 / 2
1 / 6
2/ 10
3 / 14
4 / 18
5 / 22
6 / 26
7 / 30

Answer 2

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

since, Billy started with 2 poems in his journal. Then he started writing 4 poems each day.

Thus, the line that describes the above situation is,

y = 2 + 4 x

The x -intercept of the line is (-0.5 , 0)

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

Also, if x = 1 y = 6

if x = 2 y = 10

If x = 3 y = 14

And, if x = 4 , y = 18

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

(1,6), (2,10) , (3,14) and (4,18)

Hence, with the help of the above information we can plot the graph of the line.
