[tex]m = \frac{y2-y1}{x2-x1}[/tex]
[tex]m = \frac{4-16}{-6-6} \\m = \frac{-12}{-12} \\\\m = 1[/tex]
Therefore, the slope of the line is 1. In case if you want to know the equation.
[tex]y=mx+b\\y=x+b\\4=-6+b\\4+6=b\\10=b\\[/tex]
Therefore, the equation is y=x+10 by substituting the (-6,4) or we can substitute (6,16) too.
[tex]y=mx+b\\y=x+b\\16=6+b\\16-6=b\\10=b\\[/tex]
It's the same, you can use any orders given.
Overall, the slope is 1 and the equation is y=x+10
