Answer:
-1
Step-by-step explanation:
To find the slope of a line, we can do rise over run, or y/x.
r/r = 1/1 = 1
But as you can see, the line is going down which means it's decreasing, which means that it has a negative slope
slope = -1
Hope this helped a little!

Answer:
24
Step-by-step explanation:
30% of the pie chart is pizza. 30% of 80 = 0.3 * 80 = 24
To answer, it is assumed that e here is the Euler number which is equal to 2.718. Substitute this value to the e of the second equation to get the value of b.
b = 0.5(2.718^2) = 3.6945
Then, we substitute this value to the first equation to get the value of a.
a = 4(3.6945^2) = 54.498
Thus, the answer is approximately equal to 54.5.
