To find the linear function that represents this situation, we need to determine the slope of the line using the two given data points.
Let:
-x_1 = 2350
-y_1 = 6000
-x_2 = 1750
-y_2 = 4200
The slope of the line can be calculated as:
m = \dfrac{y_2 - y_1}{x_2 - x_1}
Substitute the given values into the formula:
m = \dfrac{4200 - 6000}{1750 - 2350} = \dfrac{-1800}{-600} = 3
Now that we have the slope, we can use the point-slope form of a linear equation to write the equation of the line:
y - y_1 = m(x - x_1)
Substitute one of the points and the slope into the equation:
y - 6000 = 3(x - 2350)
y - 6000 = 3x - 7050
y = 3x - 1050
Therefore, the linear function that represents this situation is y =3x-1050
