Question 618139
Write an equation for the line parallel to the given line that contains C. 
C(3,8) y=-3x+1
**
equation of a straight line: y=mx+b, m=slope, b=y-intercept
slope of given line=-3
slope of line parallel to  given line=-3
equation of parallel line: y=-3x+b
solving for b using coordinates of given point (3,8)
8=-3*3+b
b=17
equation: y=-3x+17
