let the number of adult tickets be x and the number of children tickets be y
3x + y = 164...equ(1)
2x + 3y = 174....equ(2)
multiplying equation 1 by 3
9x + 3y = 492
subtracting equation 2 from 1
7x = 318
x = 45.43 dollars
substituting the value of x into the equation
3(45.428) + y = 164
y = 164 - 3(45.428)
∴y = 27.71 dollars

Answer: La cuenta de Milla ganaría $63 más que la cuenta de Gion después de 1 año.
Slope-intercept form:
y = mx + b
"m" is the slope, "b" is the y-intercept (the y value when x = 0)
You need to find "m" and "b".
In the table, when x = 0, y is 0, so the y-intercept is 0
y = mx + 0 or y = mx
To find "m", you can use the slope formula and plug in 2 points:
(0,0) and (1, 3)
m = 3
Slope: 3
y-intercept: 0
Equation: y = 3x
This transformation is a dilation by the scale factor of 0.5 or 1/2 because the x and y values are being multiplied by 0.5.
Hope this helps!
