Answer:

This problem is not possible.

Step-by-step explanation:

Only functions and variables can have subscripts, or the number below the first 2. If we were to take that out, then we would get a line that starts at y = 8 and goes up on the x axis.

Hope that this helps!

Find the slope of the line that passes through the points (-2,4) and (-5,-6)
natali 33 [55]

\bf (\stackrel{x_1}{-2}~,~\stackrel{y_1}{4})\qquad (\stackrel{x_2}{-5}~,~\stackrel{y_2}{-6}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-6-4}{-5-(-2)}\implies \cfrac{-10}{-5+2}\implies \cfrac{-10}{-3}\implies \cfrac{10}{3}
