Final answer:
The linear equation in standard form (Ax + By = C) can be written as 5x - y = -9.
Step-by-step explanation:
The linear equation in standard form (Ax + By = C) can be written by substituting the given values of m and b into the equation.
Given m = 5 and b = 9, the equation can be written as:
5x - y = -9
So, the linear equation in standard form is 5x - y = -9.
