Linear equations are represented by straight line.
The required graph is graph (a).
The given parameters are:
Let x represents the number of weeks, and y represents the number of words in week x.
So, we have:
Substitute 15 for Rate
The above equation means that:
The graph that represents the above ordered pair is graph (a).

Option B:
The solution to the given inequality is x ≤ 8.
Solution:
Step 1: Given expression is the inequality.
9x ≤ 72
Step 2: To find the solution to the inequality:
9x ≤ 72
Step 3: Divide by 9 on both sides of the inequality.
Step 4: The solution is x ≤ 8
The solution to the given inequality is x ≤ 8.
Hence Option B is the correct answer.
Explanation:
Perimeter of the park
= 337 m
= 33700 cm
Length of each fence panel
= 550 cm
Number of fence panel required
= Perimeter of the park/Length of each fence panel
= 33700 cm/550 cm
= 33700/550
= 3370/55
= 674/11
= 61 3/11
So, we will need 61 3/11 fence panels.
P.S. — 61 3/11 means 61 whole and 3/11. I have attached its picture, so that you understand.
