**Use a number line to find each difference.** 1) \(7 - 8\) Number line: A horizontal line with arrows at both ends, marked with evenly spaced ticks representing integers. This diagram is used to visually represent subtraction by locating 7 on the number line and moving left by 8 units. 2) \(5 - (-9)\) Number line: Similarly, this line includes evenly spaced ticks representing integers. In this case, the subtraction involves locating 5 and moving right by 9 units due to the subtraction of a negative number, which is equivalent to addition.
