Question

using the digits -9 to 9, without repeating any numbers, place a number in each box to create a system of equations that has a solution in quadrant 2. Tip: in quadrant 2, the x - coordinate is negative and the y-coordinate is positive.

Answer 1

Okay, here we have this:

Considering the provided information and options, we are going to find the requested numbers, so we obtain the following:

So first we will choose two values for x and y that meet the given tip: in quadrant 2, the x - coordinate is negative and the y-coordinate is positive.​

For our case we will take x=-1 and y=1, then we can write the following two equations:

1x+3y=2 -> 1(-1)+3(1)=2 -> -1+3=2 -> 2=2

y=7x+8 -> 1=7(-1)+8 -> 1=-7+8 -> 1=1
