Ответ:
they are parallel because they have the same slope of -2.
Step-by-step explanation:
In order to solve this you first have to clear both equations for Y in order to leave the equation in slope form:
6x+3y=9
3y=9-6x
y=3-2x
4x+2y=8
2y=8-4x
y=4-2x
Remember that the slope is the constant that is multiplying the x, so in both functions the slope is -2 when two functions share the same slope, they are perpendicular.
