Final answer:
To rewrite the equation y - 9 = 3(x + 7) in standard form, distribute the 3 to the terms inside the parentheses and then rearrange the equation so that the x term comes before the y term. The standard form of the equation is 3x - y = -30.
Step-by-step explanation:
To rewrite the equation y - 9 = 3(x + 7) in standard form, we need to distribute the 3 to the terms inside the parentheses:
y - 9 = 3x + 21
Next, let's rearrange the equation so that the x term comes before the y term:
3x - y = -30
This is the equation in standard form, where the coefficients of x, y, and the constant term are all integers.
