What does the slope mean in this context?slope:(A)7 (B)1/3 (C)-7 (D)-3Slope meaning: the water is [selected](A)added (B) removed at a rate of [selected] (A)1/3 (B)3 (C)7 (D)-7gallons per minute

The equation y 3x 7 represents the amount of water y left in a 7gallon tub after x minutes What is the slope of the line What does the slope mean in this contex class=

Respuesta :

Answer:

(D)Slope=-3

(B)Removed

(B)3 gallons per minute

Explanation:

The equation is given as:

[tex]y=-3x+7[/tex]

Comparing it with the slope-intercept form of the equation of a line:

[tex]\begin{gathered} y=mx+b \\ \text{where m=slope} \end{gathered}[/tex]

• The slope of the line = -3.

Since the slope is negative, it means the water is removed at a rate of 3 gallons per minute.
