Answer:
The answer is
<h2>

</h2>
Step-by-step explanation:
Equation of a line is y = mx + c
where 
m is the slope 
c is the y intercept
To find the equation we must first find the slope of the line.
So the slope of the line using points (-3, 7) and (9,-1) is
<h3>

</h3>
Now we use the formula
<h3>y - y1 = m(x - x1)</h3>
where
m is the slope
( x1 , y1) is any of the points given
So the equation of the line using point
 ( - 3 , 7) and slope - 2/3 is
<h3>

</h3>
We have the final answer as
<h3>

</h3>

The awnser would be 210 because 7 times 10 times 3 is 210
        
             
        
        
        
The formula of the Simple Interest is:
I=PRT
P for Principle Amount     ($1200)
R for Rate                        (5%=

 = 0.05)
T for Time in years          (4 years)
I = 1200 × 0.05 × 4
  = $240
Add the interest to the principle amount to check the balance
$1200 + $240 = $1440
