For
(x1,y1) and (x2,y2)
slope=(y2-y1)/(x2-x1)
(1,-4)
(4,2)
x1=1
y1=-4
x2=4
y2=2
slope=(2-(-4))/(4-1)=(2+4)/3=6/3=2
slope=2
The number of practice hours per week for Maranda's piano recital is 13 hours
Overall practice hours = 52 hours
Number of weeks of practice = 4 weeks
Since, the number of practice hours per week is the same ;
Number of hours practiced each week can be obtained by dividing the overall practice hours by the number of weeks of practice.
Number of practice hours per week = Overall practice hours ÷ Number of weeks of practice
Number of practice hours = (52 ÷ 4) = 13 hours
Therefore, Marana practiced for 13 hours each week.
