The line is given in the form:

Where

is the slope and

is the y-intercept.
Comparing the given line to the generic form we can see that

, which is the slope.
You could also get this/check the answer by graphing the equation.
Answer:
A: 100 cm^3
Step-by-step explanation:
Hopefully this helps!
Well first try to make the fractions into decimals or percent's to make the question easier
Are you trying to solve for c? if so c=8
The equation for a quadratic is as follows:
y = ax^2+bx+c
The first variable “a” determines whether the parabola opens up or down
The squared allows the equation to look like the parabola swoop when graphed.
The c term is the constant term
