Final answer:
Yes, (1,4) is a solution of -4x + 5y = -4.
Step-by-step explanation:
In order to determine if (1,4) is a solution of the equation -4x + 5y = -4, we need to substitute the values of x and y into the equation and see if the equation holds true.
When we substitute x = 1 and y = 4 into the equation, we get: -4(1) + 5(4) = -4. Simplifying this expression, we get -4 + 20 = -4, which is true.
Therefore, (1,4) is indeed a solution of the equation -4x + 5y = -4.
