There is 1 in. of water in a pool. The water level is increasing at 0.75 in./min . Which linear equation represents the total depth of the water, in inches, after x minutes?
y=0.75x
1+y=0.75x
y=0.75x+1
x=0.75y

Let

x-------> the time in minutes

y------> the water level in inches

we know that

the slope of the linear equation is equal to

[tex]m=0.75\frac{in}{min}[/tex]

The y-intercept is the value of y when the value of x is equal to zero

In this problem the y-intercept is equal to

[tex]b=1\ in[/tex]

the equation of the line in the slope-intercept form is equal to

[tex]y=mx+b[/tex]

substitute the values

[tex]y=0.75x+1[/tex]

therefore

the answer is

[tex]y=0.75x+1[/tex]
