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???
