Overnight, a pipe cracked and started to leak into a basement. The graph shows the depth of the water in relation to time. How many inches does the water rise each hour?
inches.

​How deep is the water after four hours? The water is
inches deep.

​How long will it take for the water to reach a depth of 80 inches? It will take
hours.

Y= -2/3x + 8 1/3

Because:

First I found the equation, y=3/2x+12
Next, to find the perpendicular equation heres what you do. The yint does not matter, it changes completely so we should just get rid of it to equal. y=3/2x Next, we changed the slope. For perpendicular lines, we flip the fraction then make it the opposite (negative to positive or positive to negative) Which would make this slope to now be -2/3 Filter that into the equation to be, y=-2/3x Now to find the yint we use this point, (11,1) We multiple the slope by the first number 11. 11 times -2/3x equals -7 1/3
The yint is the number that you need to add for -7 1/3 to equal 1. Because 1 is the second number of (11,1) This number is 8 1/3 so,

y= -2/3x + 8 1/3

Hope I wasnt too confusing
