Question

Use the mid-point for me to estimate the sales of trucks, inc. in 2004, given the sales in 2002 and 2006. As soon as the sales of trucks, inc. Cells always follow a linear pattern.

Answer 1

Given y-values y₁ and y₂, the y-coordinate of the mid-point on a straight line is given as:

$\frac{y_1+y_2}{2}$

Since it is given that the sales always follow a linear pattern, then the y-values will be:

$y_1=140,y_2=280$

Substitute into the formula for y-coordinate of mid-point and evaluate:

$\frac{140+280}{2}=\frac{420}{2}=210$

Hence, the sales of trucks in 2004 is about 210 million.
