Multiply 4 by -1. Answer: -4.
Add -4 to 3. In other words, 3-4. Which equals negative one.
The equation is true, and therefore, the coordinates (-1,3) would lie on that line.

x = -1 and y =3
4(-1) + 3 = -1
it's asking if -4 + 3 = -1 and the answer is yes..so (-1,3) is on 4x+y =1

to solve this problem put the coordinate into the equation and see if it balances
4(-1) + (3) = -1
-4+3=-1
-1=-1
so your answer is yes!
