You can use a protractor to solve for the angles
Answer:
slope is -1
Step-by-step explanation:
Slope of the line (m)=(y2 -y1)/(x2 -x1)
given
(x1, y1)=(-4 , 5)
(x2,y2)=(-7 , 8)
Now using the above formula
m =(8-5)/(-7-(-4))
m = (3)/(-7+4)
m= 3/(-3)
m=-1
therefore the slope of the line is -1
80%= .80
of means times
decrease means to subtract
75 x ,80= 60 students lost
75-60= 15 students left
