Identify the equation that represents the line of best fit on this scatter plot. a. y = -x + 2
b. y = x + 2
c. y = 5/7 x + 2
d. y = - 5/7 x + 2

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? )
