Answer:
Option (4)
Step-by-step explanation:
Equation of a line passing through a point  and with slope 'm' is,
 and with slope 'm' is,
y - y₁ = m(x - x₁)
Given → Slope 'm' = -2
Point through which the line is passing is (-1, -2)
x₁ = -1 and y₁ = -2
Therefore, equation will be,
y + 2 = -2(x + 1)
y = -2x - 2 - 2
y = -2x - 4
Option (4) is the correct option.
 
        
             
        
        
        
Answer:
fals it would be 11
Step-by-step explanation:
11 x 3 = 33
3 x 11 = 33
33 divide 11 = 3
33 divide 3 = 11
 
        
                    
             
        
        
        
B. 5:10 because 15-5=10 which is the number of pencils with erasers and the 5 left are the amount of pencils which are missing an eraser
        
             
        
        
        
I'm going to assume you mean 3 to the power negative 5.
3^-5
Use rule [ x^-y = 1/x^y ]
3^-5 = 1/3^5 = 1/243
Best of Luck!
