Answer: The below graph shows the given situation.
Step-by-step explanation:
Here x represents the number of week and y represents the total height f the plant after x weeks.
Then, According to the question,
For the first batch,
y = 2x + 4 ------ (1)
Which is the line having the x-intercept = (-2,0)
And, y-intercept = (0,4)
And, For the second batch,
y = 1.5x + 7
y = 3x/2 + 7 -------(2)
Which is a line that having x-intercept = (-14/3,0)
And, y-intercept = (0,7)
By solving equation (1) and (2),
We get,
x = 6 and y = 16
That is, the intersection point of line (1) and (2) is (6,16)
Thus, By the above explanation we can plot the solution of the system of equations (1) and (2) in the graph.
