Answer:
f(x) = x -3
Step-by-step explanation:
The y intercept is where it crosses the y axis. That value is -3
The slope is change in y over change in x
We start at the y intercept and go up +3 and to the right +3 to get to the next point.
The difference is +3/+3 = 1
The slope is 1
Putting this in slope intercept form
y = mx+b where m is the slope and b is the y intercept
y = 1x-3
or in function form
f(x) = x -3
