Question 791500
Write an equation in point-slope form for the line through the point (-2,1) parallel to the line with equation 3x - y = -9

3x-y = -9

y=3x+9

compare with equation y= mx+b

m=3 = slope
 a parallel line will have same slope of m=3
point = (-2,1)

general equation is 

y-y1=m(x-x1)
where x,1y1 are the co ordinates of the point

y-1=3(x-(-2))

y-2=3x+6

y=3x+6+2

y=3x+8
