Plz explain step by step, i'm taking adv. math (algebra) it's confusing if can't explain, plz at least give right answer ✌

perpendicular lines have negative reciprocal slopes

since x=4 has a zero slope

the slope will be undefined or y= something

since it passes thru (3.5)

y=5

Choice A

points that are on x=5 must have the x coordinate = to 5

(5, something)

Choice B  (5,0) (5,-2)

Parallel lines have the same slope x=7 has a slope of zero

so it must be a horizontal line   x = something

it can't equal y because then the slope is 1

x must equal 4

Choice D

courtesan no naked yes

hope this ^_^

do you see a nakes

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
