Question

Plz explain step by step, I'm taking Adv. Math (Algebra) It's confusing If can't explain, plz at least give right answer ✌

Answer 1

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

Answer 2

Second one only that’s the answr
