A student is measuring the length of an icicle, y, every hour, x. The icicle is currently 14 inches long and is melting at a rate of 0.9 inches per hour. Find and interpret the slope for this relationship.
A;−0.9; for every additional hour, the length of the icicle decreases by 0.9 inches
B;0.9; for every additional hour, the length of the icicle increases by 0.9 inches
C;−14; the length of the icicle when the student first measures it
D;14; the length of the icicle when the student first measures it
