question number 2 from the parcc test reads which points are on the graph of the equation -3x + 6 + 5 equals -7 select all all that apply will first thing I'm going to do is you could do this different ways you know any sets of ordered pairs the first quarter is the score in the second quarter is the walk on it and you could just simply setbacks for the X and multiply and put the wife or the Watt and then add 5 and see if you get -7 and if you do then that would be a solution this equation  first thing I'm going to do however is going to get rid of this positive off and put it in standard form where the x coordinate and Y no external item or the same side and the constants on the other side so I'm going to go ahead and get rid of by doing its inverse and subtract 5 and I subtract 5 from one side of the equation of try far from the other side keep it balanced  hear Farmers Father's Day what's a zero pair and on this side of the equal sign I have seven negative plus another five negative gives me 12 news or negative 12 and here now I have left as I've -3x + + 6 sinkholes -12 + 6 y equals dang what's up and what I'm going to do this I am going to try to call will this for you bit maybe make it a little easier to look at it let's try I guess we'll try yellow first that access when I call Access yellow and we're going to put those yellow x's in for this yellow X and multiply what will be a good color let's try green for won't do green for Waze when photo GreenWise into this Greenwald and will check the solutions for a nag of 3 Zhang of 3 is -9/8 times as a positive not knowing if it's 6 here and 6 x 6 36  36 + 9 is 45 + 45 certainly does not equal negative 12 so therefore a is not a solution to this equation Play-Doh strieby access negative to negative 2 times negative 3 is a positive 6 1410 * 600 666 does not equal -12 and therefore be is not an answer to this was not a solution was Tri-C  C1500 * -3  add negative 2 as a wine putting native to time sex we do in fact get negative 12 0 + -12 is -12 negative 12 does equal name of 12 so they 4C is one of our Solutions  Shakti I should point out that does select all that apply for whatever reason lot of students seem to miss this and they get the first answer and they stopped there but all these new Common Core tape test of a lot I'm going to say also you need to make sure that we're checking all our Solutions with that said let's check d 64 x 3 * 6 is -18  any pretty -3 x 6 we get another -18 a two- 18s is 36 which obviously does not equal negative 12 we can eliminate d checking and see what's what if we put 8 4 x with -3 * 8 is -24 and if we put - 4 watt 226 us 12 and if I'm at Nega 44 normal on 12 to 0 positive 12 I'm still at negative 12  so he is also Office Solutions Sulphur question number two are correct choices or c and e
