Tell one the lines for the given points are parallel, perpendicular, or neither. Just your answer. Line 1: (2, -3), (-4, -6)
Line 2: (-3, 2), (2, -8)

Perpendicular

Step-by-step explanation:

Given

Required

Tell the relationship between both lines

We start by calculating the slopes (m) of both lines.

For Line 1:

For Line 2:

The lines are not parallel because

However, they are perpendicular, because:

To prove this, substitute values for m1 and m2

--- Proved

answer: 20

step-by-step explanation:

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
