A school is keeping track of the number of tickets remaining for its year-end festival. The table shows the number of sales for
the first, second, third, and fourth weeks of the month leading up to the festival. Which graph could represent the data shown in the table?
Day Tickets 1 | 800 2 | 371 3 | 182 4 | 78 Please explain. I am not sure how to solve these. Thanks so much!

All you have to do is plot the points. Your dependent variable is the ticket sales, so it has to be in the y-axis. The independent variable, days, would be the x-axis. All in all, you would be able to plot 4 points corresponding to the 4 pairs of data given. Then, just connect them to obtain a graph. I used MS Excel to make the graph shown in the figure :)

Answer:
we determine that none of the ordered pair is a solution of as none of the ordered pairs satisfy the equation.
Step-by-step explanation:
Considering the equation
- Putting (-5,2) in the equation
∵ L.H.S ≠ R.H.S
FALSE
- Putting (0,-5) in the equation
∵ L.H.S ≠ R.H.S
FALSE
- Putting (5,1) in the equation
∵ L.H.S ≠ R.H.S
FALSE
- Putting (7,5) in the equation
∵ L.H.S ≠ R.H.S
FALSE
From the above calculations, we determine that none of the ordered pair is a solution of as none of the ordered pairs satisfy the equation.
as you notice above, is the first-row components from A, multiplying all the columns subsequently on B, and you add the products of that row, that gives you one component on the AB matrix
in the one above, we end up with a 2x3 AB matrix
