Answer:
Yes, it is in Standard Form.
Step-by-step explanation:
A linear function in Standard Form would look like:
Ax + By = C
where A, B, and C are real numbers.
A good way to check if a linear function is in Standard Form is by checking if the only the variables and coefficients found on one side of the equation and a real number is found by itself on the other side.
The linear function, -x + 4y = 5, has only the variables and coefficients on the left side of the function, and a real number (5) by itself on the right side.
The linear function, -x + 4y = 5, is in Standard Form.
I hope this helps. :)
