The equation for the number of arrangement from the number of guest is y = 12x + 2
The pattern is given as:
x y
0 2
1 14
2 26
3 38
The above table represents a linear function;
Start by calculating the slope (m) using:
[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]
So, we have:
[tex]m = \frac{14 - 2}{1 - 0}[/tex]
Evaluate
m = 12
The equation is then calculated using:
[tex]y = m(x - x_1) + y_1[/tex]
So, we have:
y = 12(x - 0) + 2
Evaluate
y = 12x + 2
Hence, the equation for the number of arrangement from the number of guest is y = 12x + 2
