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. −0.9; for every additional hour, the length of the icicle decreases by 0.9 inches 0.9; for every additional hour, the length of the icicle increases by 0.9 inches −14; the length of the icicle when the student first measures it 14; the length of the icicle when the student first measures it

Respuesta :

[tex]\begin{gathered} y=\text{ lenght of icicle} \\ x=\text{ hour} \\ 14\text{ inches long icicle} \\ melting\text{ rate of 0.9} \\ y\text{ = -0.9x + 14} \\ Let^{\prime}s\text{ remember the slope-equation:} \\ y=\text{ mx +b where m is the slope.} \\ \\ Then\text{ the slope here is -0.9} \end{gathered}[/tex]

The answer is: −0.9; for every additional hour, the length of the icicle decreases by 0.9 inches
