The equation of the given line y = -7x - 9 in standard form is 7x + y + 9 = 0
Equation of a line in standard form can be expressed as:
Ax + By + C = 0
Where:
A and B are coefficients.
x and y are variables of degree 1 or linear variables.
C is a constant.
All coefficients and constant term should be integers, not fractions or decimals. Furthermore, A should be a positive number.
The given equation is:
y = -7x - 9
Add both sides by 7x
7x + y = -7x +7x -9
7x + y = -9
Add both sides by 9
7x + y + 9 = -9 + 9
7x + y + 9 = 0
This is the standard form of the given line equation.
