Question

Line AB contains (0, 4) and (1, 6) Line CD contains points (2, 10) and (-1, 4). Lines AB and CD are (4 points)
Question 2 options:
1) parallel because the slopes are the same
2) perpendicular because the slopes are the same
3) parallel because the product of the slopes is -1
4) perpendicular because the product of the slopes is -1

*Help please

Answer 1

they have the same slope

Answer 2

Use the slope formula to find the slopes, which is y2-y1/x2-x1.
First line has slope: 2/1 or 2.
Second line has slope -6/-3, or 2.
Since they have the same slope, they have to be parallel.

Answer 3

A ? @M4thM1nd @ridoleor

Answer 4

for Line AB we have:
slope = (6-4)/(1-0) = 2
for line CB we have:
slope = (10-4)/(2-(-1)) = 2

as they have the same slope the are parallel
