The graph represents a linear function.
The amount left to pay after the eight month is (d) (8,y)
From the question, we have:
On the graph, we have the following observations
So, the amount left to pay, after the first month is (1,y) -- as seen on the graph
Similarly, the amount left to pay after the eight month would be (8,y)
Hence, the true option is: (d) (8,y)

Answer: x = 15 ; y = 15√2
Concept:
The given triangle in the question is a 45°-45°-90° triangle.
It is considered to be a special triangle where the ratio of side lengths is 1:1:√2, meaning that the legs that correspond with 45° are 1, while the hypotenuse which corresponds with 90° is √2.
Please refer to the attachment below for a graphical explanation.
Given:
A 45°-45°-90° triangle
Leg₁: 15
Solve:
Knowing that the ratio of the triangle is 1 : 1 : √2
<u>Find the value of x</u>
x leg correspond with 45° angle
Leg₁ correspond with 45° angle
Leg₁ = 15
∵ The given ratio is 1 : 1 for 45° angle
<u>Find the value of y</u>
y hypotenuse correspond with 90° angle
Leg₁ correspond with 45° angle
Leg₁ = 15
∵ The given ratio is 1 : √2 for 45° : 90° angle
