Answer:
1st option is the answer
Step-by-step explanation:
blue line: slope is 1 and y-intercept is 1; therefore equation is y= x + 1
red line: slope is -1 and y-intercept is -3; therefore equation is y= -x - 3
Given:
circle inscribed in a square.
Side length of the square = diameter of the circle.
Let x side length and diameter.
Area of a square = x²
Area of a circle = πr²
r = radius ; half of the diameter. = x/2
Area of a circle = π * (x/2)² or π (x²/4)
Ratio of the area of the square to the area of the circle
x² : π(x²/4) or x² / πx²/4
x² * 4/πx² = 4/π
7 times 7 is 49
7 times 6 is 42
and 7 times 2 is 14
so 49t+6r+2 would be your answer
Equations can be represented on graphs by plotting the corresponding x and y values. The graph of 
is option (B).
Given that:
First, we check the y intercept of
This is when 
So, we have:
This point is represented as: 
Next, check the equation when 
So, we have:
This point is represented as: 
From the list of given options (see attachment).
Only graph B has the and on its curve.
Hence, option (B) is correct.
