Answer:
-20b-35
Step-by-step explanation:
 
        
             
        
        
        
If Jiri is x, Pamela is x -5, and tehri ages combined would be 35 so;
x + x-5 = 35
collect the like terms
2x-5 = 35
add five to both sides
2x= 40
divide both sides by 2
x=20
Jiri's age is 20
        
             
        
        
        
Since m= slope =2, slope is rise/run, or (y2-y1)/(x2-x1), we'll make the point (6,6) = (x1,y1)
In point-slope form, y-y1 = m (x-x1) -->
y-6 = 2 (x-6)
y-6 = 2x-12
+6 = +6
 y = 2x-6
-2x = -2x
-2x+y = -6
