Which expression can be used to determine the slope of the linear function graphed below?

The answer would be the following

-4-0
———
0-2

If the 4" side of the card was scaled up to 10.5" then the scaling factor is 10.5/4 = 2.625. the 5" side would thus be of length 5 x 2.625 = 13.125 which exceeds the maximum dimension of 11". thus, it is the 5" side which is scaled up to 10.5" and the scaling fator is therefore 10.5/5 = 2.1. the scaled up length of the 4" side is thus 4 x 2.1 = 8.4"
