Line b passes through points (6, 7) and (1, 1). Line c passes through points (7, 10) and (2, 4). Are line b and line c parallel or perpendicular?

b and c are parallel lines

Step-by-step explanation:

Parallel lines have equal slopes

The product of the slopes of perpendicular lines = - 1

Calculate the slopes m of the lines using the slope formula

m =

with (x₁, y₁ ) = (6, 7 ) and (x₂, y₂ ) = (1, 1 )

= = =

Repeat with (x₁, y₁ ) = (7, 10 ) and (x₂, y₂ ) = (2, 4 )

= = =

Since slope are equal then line b and line c are parallel lines

i would say c is the best answer, hope it's right!

good luck! =)
