Hi! I have three questions that I need checked over just to make sure I understand it. Thanks! :)
1.) What is the slope of the line that passes through (5, 8) and (-2, 6)?
My answer: -2/7
2.) If Segment AB || Segment CD and the slope of Segment AB = 1/2, what is the slope of Segment CD?
My answer: -2
3.) One line passes through (2, 3) and (0, 4). Another line passes through (1, 2) and (2, 3). Determine whether the lines are parallel, perpendicular or neither.
My answer: Perpendicular
#1: I get -2/-7 = 2/7
#2: Nope. Parallel lines have the same slope.
#3: slopes are -1/2 and 1
Neither
