Answer:
Step-by-step explanation:
Let a and s represent the prices of adult and student tickets, respectively.
13a +12s = 211 . . . . . . ticket sales the first day
5a +3s = 65 . . . . . . . ticket sales the second day
Subtracting the first equation from 4 times the second gives ...
4(5a +3s) -(13a +12s) = 4(65) -(211)
7a = 49 . . . . . . . simplify
a = 7 . . . . . . . divide by 7
5(7) +3s = 65 . . . . substitute into the second equation
3s = 30 . . . . . . . subtract 35
s = 10 . . . . . . . divide by 3
The price of one adult ticket is $7; the price of one student ticket is $10.
Answer:
Option A) 
is correct
Step-by-step explanation:
The points through which the above line passes is <em>(0,8) (4,0) and (5,-7).</em>
Taking any two points and forming the equation of line,
take the 2 points as (0,8) and (5,-7).
The slope is calculated as,
Thus the equation of line is,
This can be rearanged as,
Thus, option A is correct.
The slope of the graph is y=1
