To convert the equation y + 4 = 2(x - 7) into standard form (Ax + By = C), follow these steps:
1. Distribute the 2 on the right side of the equation:
y + 4 = 2x - 14
2. Move all the terms to one side of the equation, typically with the variables (x and y) on the left side and constants on the right side:
y - 2x = -14 - 4
3. Simplify the constants on the right side:
y - 2x = -18
So, the equation y + 4 = 2(x - 7) in standard form is:
y - 2x = -18
