Answer:
None of these answers are correct.
Step-by-step explanation:
Perpendicular lines have opposite and reciprocal slopes, which means that we take the slope and we flip it. After we've done that, we change the sign.
Since the original slope is -7, first we flip it and get -1/7. Now we change the sign and get 1/7. Therefore, the perpendicular slope of this line would be 1/7
So you would divide 43.65 by 5 hours (to get 8.73), then you multiply by 7, and your final answer is $61.11

Answer
a. -3/5
b. (0,2)
c. The line is decreasing.
Explanation
In this form, the number that accompanies the x correspond to the slope and the value of the independent number to the y-intercept.
The line is decreasing because the slope is negative.
5 x 4 = 20 + 5 = 25
5 x 4 = 20 (black cats), and if you add the number of white cats to that(5) you get 25. So zoe has 20 more black cats than she does white cats
