Step-by-step explanation:
For this case we have that by definition, the standard form of a linear equation is:
We have the following equation of the point-slope form:
We manipulate the equation algebraically to convert it to the standard form:
We apply distributive property to the terms within parentheses, taking into account that:
We subtract 4 from both sides of the equation:
We multiply by 5 on both sides of the equation:
Adding 2x to both sides of the equation:
Subtracting 15 from both sides of the equation:
Thus, the standard form of the equation is:
