esc The sales of a company were $21,500 in its ist year of operation and $101, 500 in its 5th year. Let y represent the amount of sales in the xth year of operation. Assume that the data can be modeled linearly. Find the slope of the sales line, and the equation of that line in the form y = mx + b . y = mxto Using that equation, find the year of operation in which sales will surpass $200,000
