Answer:
The answer to your question is y = 2x + 11
Step-by-step explanation:
Data
Original line   y = -(1/2)x + 5
Point (-4, 3)
Process
1.- Get the slope of the new line
- Slope of the original line = -1/2
   If the lines are perpendicular, the slopes must be reciprocal
                        -1/2  reciprocal = 2
2.- Get the equation of the new line
           y - y1 = m(x - x1)
           y - 3 = 2(x + 4)
- Simplification
          y - 3 = 2x + 8
- Solve for y
         y = 2x + 8 + 3
         y = 2x + 11
 
        
                    
             
        
        
        
Answer: C
Step-by-step explanation:
A= 1/2(a+b)xh
A=1/2(7+10)x5
A=8.5x5
A=42.5
