    There are four of them and in this one, my teacher circled the answer but i have to explain to him how to get to the answer and that's why i need to show work. I didn't get it right the first time. 1.) y-2=-5/2(x+2) 2.) y+7=-x+5/2 3.) y=-4/7+2 4.) y=-5/2x-3 my teacher says that the 4th one is correct, but how to i get the answer????? that's the confusing part.

    slope intercept form is y=mx+b.

    okay first you need to write this in slope intercept for y-7=-5/2 (x+4)

    then what you would do next is use the distributive property

    which mean u multiply everything in the parenthesis by -5/2

    you would get 5/2x and then -5/2 times 4 is 20/2

    then you take the 20/2 and divide it and you get 10

    right now ur equation should look like y-7=-5/2x-10

    after tht u would subtract 7 from each side so ur answer would be y=-5/2x-3
