Ugh me i don’t wanna fail again

Step-by-step explanation:

Start with (1,2) . One of the pairs has to begin with a 1. Look around to see which set of points has a 1 for the x value.

B and C do. So all you have gotten rid of is A and D.  D looks like it might work, but it really does not. It has - 1 as it's starting point. The point must start with 1.

The next step is to find the distance between the 2 given points. The y value for the two points already on the graph is the same so they do not contribute anything to the distance. -3 and 1 are 4 units apart.

1 and ? must also be 4 units apart. Only D does. 1 and -3 are the x values 2 and 6 are the y values. The answer is B

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
