Given  
The equation is in the form

Simplify the above equation
To proof
As given in the question the equation is written in the form

By using the exponent property
 when you divide powers with the same base you just have to subtract the exponents. i.e

 y is not equal to zero.
Now apply this property to the above equation

As 

now put this in the above equation
we get

Hence proved
 
        
             
        
        
        
Answer:
y=-3x-2
Step-by-step explanation:
There is enough information to make a point-slope form equation that which we can convert into slope-intercept form.
Point-slope form is: 
We are given the slope of -3 and the point of (1,-5).

Convert into Slope-Intercept Form:
