Answer: y =   x + 1
x + 1 
Step-by-step explanation:
       First, we will find the slope. The slope of perpendicular lines are negative reciprocals. 
       In this case, the first slope is 2. The negative of 2 is -2, and the reciprocal of -2 is  .
.
       Now, we will plug in this new slope, the point given, and solve for the <em>b</em>, or the y-intercept.
y = <em>m</em>x + <em>b</em>
(-1) =  ( )(4) + <em>b</em>
)(4) + <em>b</em>
-1 =  -2 + <em>b</em>
1 = <em>b</em>
      Lastly, we will write our equation.
y = <em>m</em>x + <em>b</em>
y =   x + 1
x + 1
           The line is y =   x + 1, or y = 1 -
x + 1, or y = 1 -  .
.
 
        
                    
             
        
        
        
Answer:
a. or 
Step-by-step explanation:
Slope is equal to y1-y2 over x1-x2.
So the equation would be:

2-(-1)=2+1=3
-3-(-1)=-3+1=-2
So the answer is:

 
        
             
        
        
        
I think 517.26 
I did 10 times 3^2 (9) it equals 90. Then 90 times 3.14 and got 282.74. Then did 800- 282.74 and got 517.26
