I know that the rate of change is different, but I'm lost from there. How would I model the data in an equation?Answer by scott8148(6628)   (Show Source): You can put this solution on YOUR website!what rate of change is different? if the relation is linear, then the slope [(change in y)/(change in x)] between any two points is constant from (-10,-7) to (20,5) __ x change is 20-(-10) or 30 __ y change is 5-(-7) or 12 __ slope is 12/30 or .4 pick any other pair(s) of points to see of the slope is constant HINT -- it is
