to get the slope of any straight line, we simply need two points off of it, let's use those two in the picture below


(\stackrel{x_1}{1}~,~\stackrel{y_1}{-3})\qquad (\stackrel{x_2}{3}~,~\stackrel{y_2}{-1}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{\textit{\large rise}} {\stackrel{y_2}{-1}-\stackrel{y1}{(-3)}}}{\underset{\textit{\large run}} {\underset{x_2}{3}-\underset{x_1}{1}}} \implies \cfrac{-1 +3}{2} \implies \cfrac{ 2 }{ 2 } \implies 1

Answer: B

Step-by-step explanation: I used a graphing site named Geogebra and found the equation is -x+y=-4 and the slope is up 2, right 2 which would give us 2/2 which simplifies to 1
