Matt is showing his work in simplifying (6.2 − 1.6) − 4.4 + 7.8. identify any error in his work or reasoning. step 1: (6.2 − 1.6) − 4.4 + 7.8 step 2: 6.2 + (− 1.6 − 4.4) + 7.8 (commutative property) step 3: 6.2 − 6 + 7.8 step 4: −14 − 6 = 8 (commutative property) step 5: 14 − 6 = 8

Graph the line that represents a proportional relationship between d and t with the property that an increase of 33 units in t corresponds to an increase of 44 units in d. what is the unit rate of change of dd with respect to t? (that is, a change of 11 unit in t will correspond to a change of how many units in d? )
