Alright Tee — let's do this. Here's how to represent the sum and its inverse operation on a number line: a) Draw a number line showing the following sum: (-7) + (+9) = (+2) Step 1: Draw a number line with 0 in the center and markings for positive and negative integers. Step 2: Start at 0. To represent (-7), draw an arrow from 0 moving 7 units to the left, ending at -7. Step 3: From -7, to represent (+9), draw another arrow moving 9 units to the right. Step 4: This second arrow will end at +2. The final position, +2, is the result of the sum. b) Draw a number line to show the inverse operation of the sum above. The original sum is (-7) + (+9) = (+2). An inverse operation would undo this sum. One way to show this is to start from the result (+2) and subtract one of the numbers to get back to the other. Let's show (+2) - (+9) = (-7). Step 1: Draw a number line with 0 in the center and markings for positive and negative integers. Step 2: Start at 0. To represent (+2), draw an arrow from 0 moving 2 units to the right, ending at +2. Step 3: From +2, to represent subtracting (+9), draw another arrow moving 9 units to the left (because subtracting a positive number is equivalent to moving left). Step 4: This second arrow will end at -7. The final position, -7, is the result of the inverse operation. What's next? Send 'em 📸
