Answer:
Yes.
Step-by-step explanation:
Friend's answer is correct.
<u>Answer:</u>
Justine is correct, because the point (0,0) does not line up with the straight line that contains the other points.
<u>Step-by-step explanation:</u>
From points (-3,-8), to (-1,-4) the points make a straight line because the x coordinates increase by 1 while the y coordinates increase by 2. Up until the last y coordinate. While the x coordinate follows its pattern, the y coordinate increases by 4 when it's supposed to increase by 2.
<u>Note:</u>
Good luck with your quiz, hope I helped!
First you need to distribute that invisible -1 to (9-0). You do this because of PEMDAS. -9+0 will be your outcome first. You can disregard the zero and now multiply 10 * -9 * 5 as these have no x variable. Multiplying all of those you get -450 * 3x. Thats the simplified form of this problem. -1350x if you're teachers looking for that.
