Answer:
true
Step-by-step explanation:
If f(x,y)=x+4y then point A(-3,4) is a valid point for the given function
Answer:
This is true
Step-by-step explanation:
The best way to see if it right or wrong, the answer is you have to apply it into the equation. (-3,4) means x would be =-3 and y = 4, when you change this into the equation of the line, you would get:
x+4y=13
-3 + 4*4 = 13
-3 + 16 = 13
13 = 13
This is true
Hope this help you :3
