Y= -1/2x -1
first use the formula y2-y1/ x2-x1
then plug in (-10, 4) and (-16, 7) into the formula so it should look like 7-4/ -16 +10
that should simplify down to -1/2
Next plug one of the points into the new formula y=-1/2x +b to find B

This sort of table is called a "two-way table." One set of categories is represented in rows, another set is represented in columns. This table is filled with <em>frequencies</em>. Such tables can also display <em>relative frequencies</em> by dividing the entire table by the total of totals in the lower right corner.
