Question$f(x) = c - x$
What do all members of the family of linear functions $f(x) = c - x$ have in common?
All members of the family of linear functions $f(x) = c - x$ have graphs that are lines with slope \_\_\_\_\_\_\_\_\_\_\_\_ and y-intercept \_\_\_\_\_\_\_\_\_\_\_\_.
Sketch several members of the family.
$c = 2$ $c = 1$ $c = 0$ $c = -1$ $c = -2$
$c = 2$ $c = 1$ $c = 0$ $c = -1$ $c = -2$
$c = 2$ $c = 1$ $c = 0$ $c = -1$ $c = -2$
$c = -2$ $c = -1$ $c = 0$ $c = 1$ $c = 2$
