A relation is plotted as a linear function on the coordinate plane starting at point C at (0, −1)and ending at point D at (2, −11) . What is the rate of change for the linear function and what is its initial value? Select from the drop-down menus to correctly complete the statements.
The rate of change is Choose... and the initial value is Choose

the answer is a.

135 and 80

step-by-step explanation:

there is only one way to arrange all the eight relative to each other because they are not distinct. we have

now there are nine places to place an (and not more than one in one place).   because we have four symbols, we need to choose four of these nine places to insert an . order does not matter because the are not distinct.

thus there are 1 · c(9,4) ways, or, if we calculate it,

thus there are 126 ways to form such "words."
