B.
The slope is undefined.
A.
The slope is [ ]. (Simplify your answer.)
B.
The slope is undefined.
The slope can be found using the formula: slope = change in y / change in x.
In this case, the babysitter earns $7 for 1 hour and $28 for h hours. The change in y is $28 - $7 = $21, and the change in x is h - 1 = h - 1.
Therefore, the slope is given by:
slope = (change in y)/(change in x) = $21/(h - 1)
So, the slope is A. The slope is 21/(h - 1). (Simplify your answer if needed.)
In this case, the babysitter earns $7 for 1 hour and $28 for h hours. The change in y is $28 - $7 = $21, and the change in x is h - 1 = h - 1.
Therefore, the slope is given by:
slope = (change in y)/(change in x) = $21/(h - 1)
So, the slope is A. The slope is 21/(h - 1). (Simplify your answer if needed.)
