1. Graph is attached.
Title: Contractor 1's fee
In the real world it would mean that the total cost (y) is starting at 200 and then 50 per hour.
(1,250) means that she paid 250 for 1 hour
(2,300) means that she paid 300 for 2 hours
(3,350) means that she paid 350 for 3 hours
2. It means that contractor 2 charges 5 more per hour
it means that contractor 1 charges 50 more as a starting fee.
3. rate of change 60, this means that it changes by 60 every time.
y-2=60(x-0)
y intercept is 0
4.
a. x=210, y=10700,y=210(50)+200
b.x=195, y=195(55)+150, y=10875
c.x=185,y=185(60),y=11100
d. She should choose contractor 2 because it's the second cheapest and contractor 1 is over 200 hours.
x

Explanation:
Find a pair of factors of
56
with sum
15
.
The pair
7
,
8
works in that
7
⋅
8
=
56
and
7
+
8
=
15
Hence:
0
=
x
2
+
15
x
+
56
=
(
x
+
7
)
(
x
+
8
)
So:
x
=
−
7
or
x
=
−
8
