It is -10
Because when you take two points from the table and put it into the equation y=my+b...
So for example, take (-4,-16) from the table and substitute into x and y...
-16=m(-4) + b
And then substitute all the options given in the question, so I tried -10 first and put it in the place of m( in the equation) because m is the slope.
Then the equation would look like this:
-16= -10(-4) +b
Now solve for b
B= 24
And then check your answer by the RHS and LHS Method..
-16=-40 +24
Which is equal to:
-16=-16
There fore the the slope of this equation is 10
