Katie has a roll of ribbon that is 8 feet long. she cuts off 3 feet of ribbon and the remaining length is cut into 8 shorter pieces of equal length. what is the lenght of each shorter piece of ribbon?
y = 2x - 1
in an equation with the form y = mx + b, the slope is m. because parallel lines have the same slope, the slope of the other line is also 2. plug this back into the mx + b form to get y = 2x - 1.
x = 0, y = -2
a. she cleans 2.5 rooms per hour
b. im not sure what the equation would be
c. the point (6,15) represents 15 rooms were cleaned in 6 hours
