Y = 1/3x - 4 because y = mx + b the slope (m) is 1/3 and the y-intercept (b) is -4
        
                    
             
        
        
        
The point-slope form:

 - slope
 - slope
 - point
 - point
We have the point  and the slope
 and the slope 
Substitute:

 
        
             
        
        
        
Answer:
When Sum of square of two Sides is equal to square of third side of triangle. 
Step-by-step explanation:
Given:
Three side length of triangle are given we need find the which value to substitute for a, b, c in Pythagoras theorem.
First we will find the squares of all length, then we will check which two square of side are equal to square of third side as per Pythagoras theorem.
Hence the two side would according be a and b and third side will become c.
For example if length of triangle  is given as 6 cm, 8 cm and 10 cm.
We will first take square of all

Now we can see that 

Now by Pythagoras theorem.

Hence we can say a = 6 cm, b = 8 cm, c= 10 cm   
 
        
             
        
        
        
Answer:
irrational number
natural numbers are 0,1,2,3....
whole numbers are 0,1,2,3......  so yes
real numbers are -4,-3,-2,-1,0,1,2,3,4...... so yes
irrational numbers are pi, √2...... so this would be a no
hopefully u understand :)
