Question

hich system of equations is represented in the graph below?
A graph shows two lines intersecting in the second quadrant. One line passes through points (–1, –3) and (–3, 0). The other line passes through points (–5, 0) and ( 1, 3).

–3x + 2y = 9
x + 2y = 5

3x – 2y = 9
–x – 2y = 5

3x + 2y = –9
x + 2y = –5

3x – 2y = –9
x – 2y = –5

Answer 1

analyze the two line, deduce their ecuation and see if they're true :)

Answer 2

idk how to do that

Answer 3

Let's do this together:
We will analyze the first line:
Let:
\[a \epsilon l _{1}/a(-1,2)\]
The only thing I did was taking a point that belongs to the line, and I will take the point that is x-intersection: (-5,0)
Let's first calculate the slope:
\[m=\frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }\]
So let's replace:
\[m=\frac{ 2-0 }{ (-5)-(-1) }\]
so m1=-1/2
