for fine and equation line parallel you need to know the equation line
[tex](y-y_1)=m(x-x_1)[/tex]we can say the line is parallel when the equations of the lines have the same slope so the slope of the equation shown in the question is m=(-3/2) so the equation that we will obtain most have a slope equal to (-3/2)
Using the equation line and the point c we can obtain
(y-(-2))=(-3/2)(x-6)
y+4=(-3/2)x+9
y=(-3/2)x+9-4
Finally, the equation line parallel to y=(-3/2)x+6 is
y=(-3/2)x+5
