Answer:
<h2>k = -1</h2>
Step-by-step explanation:
We have the point (5, k) and the equation 2x + y = 9.
Put the coordinates of the point ot the equation:
x = 5, y = k
2(5) + k = 9
10 + k = 9         <em>subtract 10 from both sides</em>
10 - 10 + k = 9 - 10
k = -1
 
        
             
        
        
        
Answer: y=-2x+8
Step-by-step explanation: Write a table of values where for every x y goes down 2 to find the y intercept (0,8) so it would be 8. The slope is -2 and that is all you need to write the equation.
 
        
             
        
        
        
Let  the sons age be x years then
- the fathers age is  2x + 5 years, So:-
2x + 5 - x =  25
x = 25 - 5 = 20
The father is 2 (20) + 5 = 45 years answer
