Answer:
lines are parallel
Step-by-step explanation:
• Parallel lines have equal slopes
• Perpendicular slopes are the negative reciprocal to each other
Calculate the slopes m using the slope formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 3, - 1) and (x₂, y₂ ) = (2, 4)
m = = = 1
repeat using
(x₁, y₁ ) = (2, - 6) and (x₂, y₂ ) = (7, - 1)
m = = = 1
Since slopes are equal then the lines are parallel
