Question

A line contains points (-4, 2) and (0, -4). Another line graphed in the same coordinate plane contains points (4, 3) and (-5, -3). Based on the slopes of these lines, are they parallel, perpendicular or neither?

Answer 1

Parallel lines: same slope
Perpendicular lines: negative inverse slope

Answer 2

inverse slope

Answer 3

its Parallel

Answer 4

What did you get for the slope of the first line?

Answer 5

Inverse slope means they are perpendicular.
For Example If a line has slope 3 and other has -1/3 then these two lines are perpendicular.

Answer 6

so it will be Parallel

Answer 7

What did you get for the slopes?

Answer 8

Yes if the slopes of both the lines are same then lines are parallel.

Answer 9

??????????????

Answer 10

You have to find the slope of both lines, do you know how to do that?

Answer 11

no it has to be perpendicular

Answer 12

2/4

Answer 13

I gotten 2/4 and 1

Answer 14

-3/2 and 2/3.
2/3 is negative reciprocal of -3/2.So Lines are perpendicular.

Answer 15

how 2/4 and 1 lvasquev462? when there is a formula to find slope which is:
y2-y1/x2-x1.
So -4-2/0-(-4)=-6/4=-3/2

Answer 16

Similarly find the slope of second equation.Which I got as 2/3.
So (m1)(m2)=-1.Then lines are perpendicular.
where m1=slope of first equation
and m2=slope of second equation.

Answer 17

You remember formula (m1)(m2)=-1 to check either lines are perpendicular or not.ok
