To complete the number line model, Jones should draw an arrow starting at 8 and connecting to -7. The arrow will show that they need to move in the negative direction to connect the two numbers. This movement represents subtracting 15 from 8, which results in -7. Therefore, the answer is -7.
Jones uses the subtraction algorithm to subtract 8−15 and gets the answer −7 . They want to connect this expression and answer to a number line model. How should they complete their number line model to show why the answer is −7 ? (2 points) Jones should draw an arrow starting at that connects to . The arrow will show that they need to move in the negative direction to connect the two numbers. Therefore, the answer is −7 .
