You have a friend who needs to know how to use the slope and y-intercept a) to write an equation and b) to draw a graph.

Give the detailed steps so that your friend can accurately write the equation as well as draw the graph from your description.
Thank you

I have to answer questions about latitude and longitude, but I just keep mixing them up!

Is this right?

Latitude example

15Degrees East, because latitude is east and west of the prime meridian

Longitude example

15Degrees South, because longitude is north and south of the equator


is that right? if not, please correct me in my form of writing it

like "15 Degrees South because bla bla bla"

PLEASE HELP!

I am given a 2-by-2 matrix A (0,8 / 5,7) which I am asked to write as a product of elementary matrices and then write the inverse of A as aproduct of elementary matrices. So I turned A into reduced row echlon form using the following steps:

-Switch R1 and R2
-1/5 * R1
-1/8 * R2
- (-7/5) * R2 + R1 into R1

So the elementary matrices are:
(0,1 / 1,0) * (1/5,0 / 0,1) * (1,0 / 1/8,0) and (1,-7/5 / 0,-7/5)

Right?

Then the inverse of A as a product of elementary matrices is just the inverse of each of (1,-7/5 / 0,-7/5) * (1,0 / 1/8,0) * (1/5,0 / 0,1) and (0,1 / 1,0).

Does this make sense? Because I keep getting the wrong answer and I don't know where I've gone wrong....
