Write the equation of the line through the point (2,-5) that are parallel and perpend

Is x= -5 the answer?

Write the equation of the line through the point (-7,-9) that are parallel and perpendicular to y = -12. Sorry

Sorry again the point is not (-7,-9) it is actually (2,-5)

What do you know about the slopes of two parallel lines?

What do you know about the slopes of two perpendicular lines?

How do you find the equation of a line if you know its slope and the co-ordinates of a point on the line?

And why did you put this in intermediate algebra?
 
I think the problem is actually this, so we're all on the same page:

Write the equations of the lines through the point (2, -5) that are parallel and perpendicular to y = -12?
​

So we want two equations. I would start by asking, in what direction does the line y = -12 go? Then, in what direction is a line that is parallel to it? How about a line perpendicular to it?

Then we can consider slopes (where relevant), and equations.

Your first answer was partly correct, now that we know the question! You just have to give two answers, and identify which is which.

Please explain how to get the answer, I am just so confused. Truth is my classmate gave me x=5 but I don't know how he got it.

Can you draw y= -12? Do that 1st and then we'll proceed. The LINE y=-12 is the collection of all points whose y value = -12

if you can't upload a picture then describe in words how to graph y=-12

My friend gave me that number(dunno how he got it) I am thinking the same thing?

We truly want to help. But you need to pose your questions carefully (tapatalk seems to be a disaster). You also need to try to answer the questions given to you by the tutors. Telling us you are confused does not help us figure out where and why you are confused. Answer the questions we ask so that we can tell where you need help.
