Consider the line y = x+8. What is the slope of a line parallel to this line?
What is the slope of a line perpendicular to this line?

parallel is 1 and perpendicular is -1

Step-by-step explanation:

parallel lines have the same slope and perpendicular have the opposite and negative of the slope.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

7

step-by-step explanation:

i'm assuming you need to figure out how many campers go into each tent.

i got the answer by:
