Answer:
perpendicular
Step-by-step explanation:
You want them to be in the same form first (aka y=mx+b)
y=7x+2 is already in that form so you just need to change x+7y=8. First subtract x from both sides and then divide both sides by 7 to get y by itself:
x+7y=8
7y=-x +8
y= -x/7 + 8/7
To be able to tell if a line is perpendicular or not is to look at the slope: if the slope of one equation is the "opposite" version of the other, they are perpendicular.
The slopes are -x/7 and 7x so yes, they are perpendicular
** if they're parallel they will have the same slope and if they are neither they won't have a similar slope at all
