The sales of a small company were $60.000 in its fourth year of operation and $88,000 in its sixth year. Let y represent sales in the xth year of operation. Assume that the data can be approximated by a straight line. (a) Find the slope of the sales line, and give an equation for the line in the form y = mx + b. (b) Use your answer from part (b) to find out how many years must pass before the sales surpass $90,000 (a) The slope is |and the equation sy (Type integers or decimals.) (b) The sales will surpass $90,000 in years (Round up to the nearest year) 2 Find an equation in slope-intercept form for the line Through (4,9), m = -7 The equation of the line is
