For each expression in the table, select which number line model, if any, can be used to represent the expression. ​Select all appropriate cells in the table. Expression Neither number line model can be used to represent the expression. -2+4−2+4 -2-4−2−4 -2-\left(-4\right)−2−(−4) -4+2−4+2 -4-\left(-2\right)−4−(−2)

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
