Answer:
Sara read 17 more
Step-by-step explanation:
81-64=17
64+17=84
17 pages
Sara read 81 pages while Colin read 64.
The difference between these two is 17.
81 - 64 = 17
{3x=2y+6y=x+2=3
slope of the line is 0
given points are:
(-3 , 2)=(x1 , y1)
(4 , 2)=(x2 , y2)
slope =y2 - y1/x2 - x1
=2-2/4-(-3)
=0/4+3
=0/7
=0
