Can someone help explain this to me? Ship A receives a distress signal from the southwest, and ship B receives a distress signal from the same vessel from the north. At what location is the vessel in distress located? Describe how you arrived at your conclusion using complete sentences. You must show all work in order to receive credit. A coordinate graph shows two points labeled 1,1 with an arrow pointing N and 3,4 with an arrow pointing SW.

    so when they say from the north and southwest these are exact angles they are giving us

    you want to see where a vessel could be such that it is exactly SW from that upper ship and exactly north from the bottom ship

    I have to describe my steps of how I figured it out I can't submit pictures, so I would put that I first connected the line down in the southwest 'ship' right?

    that picture is just to help you get an idea on how to get the points exactly

    something exactly south west means 45 degrees downward

    which happens with lines of slope 1

    and something exactly north means a vertical line

    so you want to draw a vertical line from point (1,1) and a slope 1 line from point (3,4) and see their intsersection

    Do you get why southwest was slope 1 line?

    oaky well just to clear it up, think about what 45 degrees means for the horizontal and vertical length in a triangle

    so samy thing here it must mean the change in x and change in y is the same, so slope is 1
