write an equation for each line.then grapgh the line.
through (2,1) and parallel to y=-3x+1
---------------
Parallel to y=-3x+1 means the slope = m = -3
---------
The form of the line is y = mx + b
When y=1, x=2, and m=-3 allows you to solve for "b":
1 = -3*2 + b
b = 7
---------
EQUATION:
y = -3x + 7
