answer:

Step-by-step explanation:
slope-intercept formula ==>

is slope , and
is y-intercept
to find the slope you need to start at the y intercept and go 3 units up and 1 unit left. and if you repeat it again, until you reach the top of the graph and that would make partial of the line.
so, the slope is
, so if you plug it in it would look like this

A D D I T I O N A L I N F O
then you find the y-intercept which would be where the line intersects at the y axis, which is -10. plug the number into the equation

and that would make our final answer.
hope this helps! correct me if there is anything wrong ❤ from peachimin
