Water Tank The graph relates the height of the water
in a tank y (in inches) to the volume of
the water x (in gallons).

a. Is the relationship proportional? Explain.
Height (inches)
b. Write an equation of the line. Interpret
the slope.
0 10 20 30 40 50 60 70 80 90 x
Volume (gallons)
c. What is the height of the water in the tank
when the volume is 250 gallons?

step-by-step explanation:

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

where is the figure

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
