Answer:
y = 5/2 x+19
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
y = 5/2 x+b
Substituting the point into the equation
4 = 5/2(-6) +b
4 = -15+b
Add 15 to each side
19 =b
The equation is
y = 5/2 x+19
(15,-10) (17,2)
(2+10)/(17-15)= 12/2 = 6
The slope is 6
Answer:

Step-by-step explanation:
Textbooks = X
Notebooks = Y
N+2
n+4
n+6
n+2+n+4+n+6
3n+12=-6
3n=-18
n=-6
the value of the greatest integer is -2
Step-by-step explanation:
Let adults = a and children = c,
(1) a + c = 1100
(2) 48a + 23c = 45300
From the (1) equation, a = 1100 - c
Then substitute a = 1100 - c into (2),
48(1100 - c) + 23c = 45300
52800 - 48c +23c = 45300
-25c = -7500
c = 300
Substitute c = 1500 into a = 1100 - c,
a = 1100 - 300
a = 800
Therefore, 800 adults and 300 children bought the tickets
