Step-by-step explanation:
given,
point = ( -10, -8 ) and ( -8, -16 )
we know,
slope = y2 - y1 / x2 - x1 
x1 , y1 = (-10 , -8 )
x2 , y2 = ( -8, -16 )
after inserting the values we got,
→ -16 - (-8 ) / -8 - (-10)
→ -8/2 → -4
therefore, slope of line is -4.
hope this answer helps you dear...take care and may this answer helps you dear!.
 
        
             
        
        
        
Of means multiplication. So the question is 1/3 X 1 1/2. First make 1 1/2 improper: 3/2. Then multiply the numerators (top numbers) and denominaters (bottom numbers): 1x3=3, 3x2=6, =3/6. Now simplify 3/6=1/2. Then multiply that by 2, since he used 2 pieces: 1/2x2=1. John used 1 meter :)
        
             
        
        
        
Answer:
B) 
 x units
Step-by-step explanation:
Let quadrilateral KMPT be a rectangle with dimensions 12 units by 8 units. Then its perimeter would be equal to:
Perimeter of a rectangle = 2 (l + b)
where: l is the length = 12 units and b is the breadth = 8 units. So that:
Perimeter of KMPT = 2 (12 + 8)
                                = 40 units
Dilating KMPT by a scale factor of 
 would create K'M'P'T' of dimensions; 
 × 12 units by 
 × 8 units. Thus, the dimensions of K'M'P'T' would be 9 units by 6 units.
Perimeter of K'M'P'T' = 2 (l + b)
                                   = 2(9 + 6)
                                   = 30 units
Comparing the perimeters of KMPT and K'M'P'T', the perimeter of K'M'P'T' would be  
 × perimeter of KMPT.
Therefore, if the perimeter of KMPT is x units, then;
          perimeter of K'M'P'T' = 
 * x units
                                             = 
x units
