Plz 1. Giants tickets are original $75 per ticket. This week they are on sale for 20% off. What is the sale price?

2. After the Giants won the Superbowl in 2012, $75 were marked up 18% what was the new selling price?

c + a = 525multiply by -3

3c + 7a = 2775

-3c - 3a = - 1575 (result of multiplying by -3)

3c + 7a = 2775

add

4a = 1200

a = 1200/4

a = 300 <== adult tickets sold

Step-by-step explanation:

To find the slope of a line when given two points, you must create an expression using the formula, change in y divided by change in x. This means subtracting one y-value from another and then dividing the difference by the difference of the two x-values.

Y1 - Y2 / X1 - X2

2 - (-5) / 4 - 0

7/4

Therefore, the slope of the line is 7/4.

Hope this helps! :)
