Answer:

Step-by-step explanation:
Since we know that you write 17 text messages a week. 17 will be our constant number, now then after you said for x weeks.
Meaning that x would be our variable cause we can put an input of any number, then put it next to 17 because that is how many times you text a week.
17x = y
17 (how many times you text per week) x (how many weeks) = y (texts in total)
-3(x-1)/x would be your answer
Answer:
Slope is -3
Step-by-step explanation:
Using the formula (y2 - y1)/(x2 - x1), we can find that the ratio is -6/2. When simplified, it comes out to -3
Since x and y are directly proportional , so x = ky
6 = 42k
k = 6/42 = 1/7
12= (1/7)y
y = 84
Lat is up and down(Y) and long is side to side (x)
