Step-by-step explanation:
Np bro, I've dealt with these all through 7th XD
 
        
                    
             
        
        
        
To make the equation easier to look at change it to this: 
y = 15 - 3x 
To find the x intercept say y = 0. 
0 = 15 - 3x 
Subtract 15 from each side. 
-15 = -3x 
Divide each side by -3. 
5 = x <–––– x-intercept
The y-intercept of the equation is 15.
Hope this helps!
