Use the slope formula.
Y2 - Y1 / X2 - X1
(-7 - 5) / (9 - -2)
(-12) / (11)
So answer: slope(m) = -12/11
You have to find the unit rate
SO..
7.70 / 154 = 0.05
So it cost her 0.05 cents for each text.
So then you divide $ 5.25 by the unit rate to get the number of text
5.25 /0.05 = 105
so she sent 105 text
To check it you just multiply the unit rate by the number of text you got and you show come up with $ 5.25
0.05 x 105 = 5.25
12 is the answer

Answer:
Out of town teenagers = 30
Step-by-step explanation:
Given that,
Total number of teenagers at a swim meet = 50
Let there are 2x locals and 3x out of town participants. The ratio of locals to out-of-town participants is 2:3.
ATQ,
2x+3x = 50
5x = 50
x = 10
Out of town teenagers = 3x
= 3(10)
= 30
Hence, there are 30 teenagers travelled from out-of-town to the swim meet.
