Write an equation in point-slope form for the line through the point
(-2,1) parallel to the line with equation: 3x - y = -9; and what are the coordinates needed to graph the two equations on one set of axes?
---------
Find the slope of the given line:y = 3x+9
slope = 3
-------
Every parallel line must have slope = 3
.......
Form y = mx + b
Solve for "b":
1 = 3*-2 + b
b = 7
------
Equation:
y = 3x + 7
