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
