- the formula that represents the equation point- slope is the following y-y1 = m(x-x1) where the point is given (-8,-3) and the slope is -1/9
- then you mus substitute the values in the equation y-(-3) = -1/9[(x-(-8)] , resolving it y+3= -1/9 ( x+8) , y+3 = -1/9x+9/8, y = -1/9x +9/8-3, y = -1/9x-15/8
of this form the equation that represent the form point-slope is
- y+3= -1/9 ( x+8)

Three machines fill 40 boxes in an hour. One machine can fill 40/3 boxes in an hour. Following the second part of the problem, one machine would take 150/40/3 = 11.25 hours to fill 150 boxes. Machines and time are inversely proportional. Then, it would take 11.25 * 1/5=2.25 hours for 5 machines to fill 150 boxes.
