y-(-2) = -5/7(x+5)well first what you do is distribute the -5/7 through (x-5) to get -5x/7 +25/7.(remember that the sign changes. the negative is changed to a positive because it is being multiplied by another negative and the positive is being changed to a negative because it is being multiplied by a negative.)now your problem isy-(-2)= -5x/7 + 25/7since there are two negative signs next to eachother in y-(-2) we can turn it into y+2.so now the problem is y+2= -5x/7 + 25/7now subtract 25/7 from y+2.you have to change 2 into a fraction so 25/7 can be subtracted. so multiply 2 by 7/7 to get 14/7. now you have 14/7 -25/7 which equals -11/7.now it isy-11/7 = -5x/7now add 11/7 to both sides to get y by itself and you gety=-5x/7 + 11/7
