Answer: Third option.
Step-by-step explanation:
<h3>
The exercise is actually: "Identify the variation as direct, inverse, joint or combined: 
"</h3><h3>
</h3>
For this exercise it is important to remember that, by definition, a Joint variation is that variation in which one variable depends on two or more variables and there are a direct relation between these variables.
In this case, you have the following equation given in the exercise:
Let's assume that "r" and "h" are variables.
You can identify that:
- The variable "V" depends on the variables "r" and "h".
- The variables are related directly.
So, based on this, the variation can be read as:
<em>"V" varies jointly with the square of "r" and "h".</em>
Therefore, you can conclude that the given variation is: Joint.
Answer:
point-slope form: y - 1 = -4/5(x - 8)
slope-intercept form: y = -4/5x + 7.4
Step-by-step explanation:
Find slope using the points (8, 1) and (-2, 9):
m = (y₂ - y₁) / (x₂ - x₁)
= (9 - 1) / (-2 - 8)
= 8 / -10
m = -4/5
Find y-intercept using slope m from above and anyone of the given points, let's use (8, 1):
y = mx + b
1 = -4/5(8) + b
1 = -6.4 + b
b = 7.4
Use slope m and y-intercept b above to form equation of line in slope-intercept form:
y = mx + b
y = -4/5x + 7.4
For point slope form use slope m from above and a point, again let's use (8, 1):
y - y₁ = m(x - x₁)
y - 1 = -4/5(x - 8)
