If negative 20 equals 168, negative 15 equals 153, negative 10 equals 138, negative 5 equals 123, 0 equals 108, 5 equals 93, 10 equals 78, 15 equals 63, 20 equals 48, then what is the rule???
Tables:
X: -20 -15 -10 -5 0 5 10 15 20
Y: 168 153 138 123 108 93 78 63 48
How do I get from X to why, wat is the rule to get y using the number x?
Also, what is the pattern in the informatio above???
y= -3x + 108
oh wait nevermind
haha actually that's the correct answer
Please help me with solving equations with rational numbers. i have struggled in math all my life. I desperately need help with my homework.
Thank you

To determine the rule or pattern in the given information, we can observe the relationship between the X-values and the Y-values. Let's analyze the pattern step by step:
1. Looking at the X-values, we can see that they increase by 5 each time: -20, -15, -10, -5, 0, 5, 10, 15, 20.
2. Now, let's examine the Y-values. When we subtract 60 from each Y-value, we can notice that they decrease by 15 each time: 168 - 60 = 108, 153 - 60 = 93, 138 - 60 = 78, and so on.
From this analysis, we can deduce that the rule or pattern is as follows:
To find the Y-value (let's call it Y), subtract 60 from the X-value (let's call it X), then subtract 15 for each 5-unit increment of X. Therefore, the mathematical relationship can be represented by the equation:
Y = 108 - 15 * (X / 5)
This equation will provide you with the Y-value for any given X-value within the range of -20 to 20.
Regarding the pattern, we can observe that for every increment of X by 5, the corresponding Y-value decreases by 15.
