Avenue can sell 850 tickets per concert. for an upcoming concert, they have been selling 25 tickets a day. write a linear function that represents the number of tickets remaining at a given time.

The linear function is equal to

Step-by-step explanation:

Let

y -----> the number of tickets remaining at a given time

x -----> the time in days

we know that

The linear equation in slope intercept form is equal to

where

m is the slope and b is the y-intercept (original number of tickets)

In this problem we have

----> is negative because is decreasing

substitute

Convert to function notation

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
