Question 956773

Find x or y.
(-12, 9), (x, -2); slope = -1/2

Can I see the work provided too?
<pre>Use the slope formula: {{{m = (y[1] - y[2])/(x[1] - x[2])}}} to determine {{{x[2]}}}, given:
Slope, or {{{m = - 1/2}}}
{{{x[1]}}} = {{{- 12}}}
{{{x[2]}}} = {{{x}}}
{{{y[1]}}} = {{{9}}}, and
{{{y[2]}}} = {{{- 2}}}
