Answer:

Step-by-step explanation:
Here we are given two coordinates through which our lines passes through. Now we are going to use the two point form to find the equation of the line. 
The two point form is given as 

Here we are given two coordinates . Thus replacing them in the formula and simplifying it will give us the equation of the line. 




adding x and 6 on both sides we get

Hence this is our equation of the line passing through (5,6) & (4,7)
 
        
             
        
        
        
For ex:
U have 4/8 - 6/2 u would probably have to use KCF- Keep Change Flip 
So then it’ll be 4/8 + 2/6 
U kept the 4/8 then u changed the subtraction to addition and u flipped the 2 to the numerator and the 6 denominator.
Idk my dude this is what I can think of
        
             
        
        
        
180 - 64 = 116
116 / 2 = 58 :)
Check: 58 + 58 + 64 = 180
