Lines ab and cd having the following points: a(2,4) b(9,8) c(-1,2) and d(3,-5). are the lines parallel, perpendicular, or neither

perpendicular

Step-by-step explanation:

Calculate the slopes m of AB and CD using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = A(2, 4) and (x₂, y₂ ) = B(9, 8)

m = =

Repeat with

(x₁, y₁ ) = C(- 1, 2) and (x₂, y₂ ) = D(3, - 5)

m = = -

The slopes are not equal, hence AB and CD are not parallel

The slope are negative inverses of each other, hence

AB and CD are perpendicular

boxplot e is the answer

.there can be infinite values of m and n that can satisfy the above equation. for each value of m of m or n. there maybe infinite sets of solution for the above
