FIND THE SLOPE The line passes through (0,1) and (2,0) Use formula of the slope to find the slope m = (y₂ - y₁)/(x₂ - x₁) m = (0-1)/(2-0) m = -1/2 The slope is -1/2
FIND THE Y-INTERCEPT The y-intercept is the value of y when the line intersects y axis. The line intersects y axis in point (0,1). The value of y is 1. So the y-intercept is 1.
Time to fit 7500 cars = 7500 * 1.25 hoursnumber of hours available in week = 40 hoursnumber of workers needed = 7500* 1.25 / 40 = 234.4number required = 235
