Patterns, equations, and graphing challenge
~10 min
Students identify a rule, write matching values, and place ordered pairs on a graph.
Matching Rules to Tables
Rule: y = x + 4
- If x = 1, then y = 1 + 4 = 5
- If x = 2, then y = 2 + 4 = 6
- If x = 3, then y = 3 + 4 = 7
A rule shows how to find the output value (y) when you know the input value (x). You can find the missing y by applying the rule to the x number.
💡 If the rule is y = x + 3, just add 3 to your x value.
