Answer:
gallons = dependent
minutes = independent
Step-by-step explanation:
independent variable = the variable being manipulated/changed
dependent variable = the variable being changed as a result
gallons = dependent (of the minutes of running water)
minutes = independent (affecting the gallons)
Step-by-step explanation:
Step 1: Draw your trend line.
You begin by drawing your trend line. You want your trend line to follow your data. You want to have roughly half your data above the line and the other half below the line, like this:
trend line equation
Step 2: Locate two points on the line.
Your next step is to locate two points on the trend line. Look carefully at your trend line and look for two easy to figure out points on the line. Ideally, these are points where the trend line crosses a clearly identifiable location.
For the trend line that we just drew, we can see these two easily identifiable points.
trend line equation
We can easily identify these two points as (3, 3) and (12, 6).
Step 3: Plug these two points into the formula for slope.
The formula for slope is this one:
trend line equation
We can label our first point as (x1,y1), and our second point as (x2,y2). So our x1 is 3, our y1 is 3, our x2 is 12, and our y2 is 6. Plugging these values into the equation for slope and evaluating, we get this:
trend line equation
So our slope is 1/3.

Answer:$270
Step-by-step explanation:
I=PRT
Interest=principal times rate times time
Principal=1500
Rate=9%=0.09
Time=2
I=1500 times 0.09 times 2
I=1500 times 0.18
I=270
Interest=270
Total is 1500+270=1770 total paid
Solution of the equation 
is x=4 and x=-12
Step-by-step explanation:
We need to solve the equation:
Solving:
Multiplying terms on the left hand side
Now factorizing:
So, solution of the equation is x=4 and x=-12
