Question 263496
I assume you mean:  y-3 = -2(x+3)
.
<b>Slope-Intercept Form:  y = mx + b</b>
.
Muliply through to remove the parentheses:
y-3 = -2x -6
.
Add 3 to both sides:
y = -2x -3
.
<b >Standard Form:  Ax + By = C</b>
y-3 = -2(x+3)
y-3 = -2x -6
.
Add 2x to both sides:
2x + y -3 = -6
.
Add 3 to both sides:
2x + y = -3
