Question

Find the slope of each line and then determine if the lines are parallel, perpendicular or neither. If a value is not an integer type it as a decimal rounded to the nearest hundredth.Line 1: passes through (-8,-55) and (10,89) the slope of this line is Answer.Line 2: passes through (9,-44) and (4,-14) the slope of this line is Answer.The lines are Answer

Answer 1

For line 1 =

The coordinates given are (-8,-55) , (10,89)

The slope of the line is

$m=\frac{89+55}{10+8}=\frac{144}{18}=8$

For line 2 =

The coordinates given are (9,-44) , (4,-14)

The slope of the line is

$m=\frac{-14+44}{4-9}=\frac{30}{-5}=-6$

The lines are not perpendicular or parallel because the slope of the lines does not satisfy the condition of perpendicular or parallel slopes.

Hence the answer is neither.
