The slope of the line would be -1/2.
To find the slope we need to make the line in the form y = mx + b:
2x + 4y + 7 = 0
2x + 4y = -7
4y = -2x - 7
÷ 4
y = (-2/4)x - (7/4)
-2/4 simplifies to -1/2.
I hope this helps!

Step-by-step explanation:
Answer:
Step-by-step explanation:
Use the formula Sum = (a + L)*n/2
The tricky part is n. That's the number of terms between 1 and 99 inclusive.
n = 99 -1 + 1 = 99
n = 99
a = 1
L = 99
Sum = (1 + 99)*99 / 2
Sum = (100)*99/2
Sum = 4950
Using exponential function concepts, it is found that the second function has a greater rate, as 0.8 > 0.2.
<h3>What is an exponential function?</h3>
It is modeled by:

In which:
- a is the initial value, that is, y when x = 0.
- b is the rate of change, as a decimal.
Function 1 is given by:

Hence the rate is b = 0.2.
Considering the values on the table, function 2 is given by:

Hence the rate is b = 0.8.
Hence, the second function has a greater rate, as 0.8 > 0.2.
