Answer:
see explanation
Step-by-step explanation:
Consider the left side
1 + cot²A
= 1 + 
= 
= 
= cosec²A
= right side, thus proven
 
        
             
        
        
        
Answer:
D. 10
Step-by-step explanation:
To find the slope of the equation, we first need to put the equation into slope-intercept form:
y=mx+b
So first, we need to get y by itself. 
10x-y=2
Subtract 10x from both sides.
-y=-10x+2
Then, divide -1 on both sides. 
y=10x-2
Slope=10
 
        
                    
             
        
        
        
Answer 
False
FalseThe correct point slope form passing through points (x1,y1) is (y-y1)=m (x-x1)(y−y1)=m(x−x1)
