Answer:
Step-by-step explanation:
To find the slope, use 2 coordinates from your table and plug them into the slope equation, which is
Let's use the first 2 coordinates (-1, -2) and (0, -4). Plugging into the slope formula:
Therefore, we know that the slope is -2.
The y-intercept exists where x = 0. We see from our table that when x = 0, y = -4. So the y-intercept is -4.
To write our equation, we will use the slope-intercept form of a line, which is
y = mx + b, where m is the slope and b is the y-intercept. Plugging in both our values for slope and the y-intercept:
y = -2x - 4
Use algebra to set up 2 equations.
Assign c as number of tickets for CATS and w for number of tickets of WICKED
c + w = 2700
c / w = 7 / 11
Then solve for one of them in the first equation
c = 2700 - w
Then put this value for c into the 2nd equation
(2700 - w) / w = 7 / 11
Now cross multiply the numerator by denominator of both numerator and denominator pairs
7w = 11 x (2700 - w)
7w = 29700 - 11w
Now solve for w
7w = 26700 - 11w
Add +11w to both sides
18w = 29700
Now divide by 18 on both sides
w = 1650
Then c is the remainder of that ... 2700 - 1650 = 1050
You can also check because 7 / 11 = 1050 / 1650
