Question

fill in the missing number to complete the linear equation that gives the rule for this table.
x | y
4 | 1
5 | 2
6 | 3
7 | 4
y = x − \square
submit

Explanation:

Step1: Use the first pair (x=4, y=1)

Substitute into \( y = x - \square \), we get \( 1 = 4 - \square \).

Step2: Solve for the missing number

Rearrange the equation: \( \square = 4 - 1 \). So \( \square = 3 \). We can check with other pairs, like x=5, y=2: \( 2 = 5 - 3 \), which is true.
