A 2-column table with 2 rows. Column 1 is labeled x with entries negative 7, 0. Column 2 is labeled y with entries 0, 1.

Gre4nikov [31]

Answer:

1/7.

Step-by-step explanation:

To solve this, we can simply use an equation to solve for the slope using two points:

$m= \frac{y_{2}-y_{1} }{x_{2}-x_{1}}$ We can substitute our points giving us:

$m= \frac{1-0}{7-0}$ $= m= \frac{1}{7}$

The slope of the graph is 1/7!
