Answer:

Step-by-step explanation:
The equation in slope-intercept form is given by:

where
is the slope and
is the y-intercept.
The given line passes through so many points. We can use any two these points to find the slope of the line.
The line passes through
and
.
The slope is given by;
.
.
.
The y-intercept from the graph is 
Our equation finally becomes;

Did u type the equation wrong none of these graphs match I believe the intercept would be 2
Solve for f:
-22=2f, so f=-11.
Answer:
