Answer:
-1
Step-by-step explanation:
Answer:
1. y = 7x. This is an example of direct variation as the value of y also increases if the value of x is increased.
2. xy = 24. This is an example of inverse because the value of y is decreased when x is increased.
3. F = 4/R. This is inverse variation for the same reason as number 2.
4. m/n = 4. Direct variation. For the same reason as number 1.
5. i = 2pr. Joint variation. The value of i is dependent on the values of two other variables.
6. R = cl/r². Joint variation.
7. A = pir². Direct variation. I believe pi here is for π, leaving only A being dependent only to value of r.
8. V= pir²h. Joint variation.

Answer:
<em>-3</em>
Step-by-step explanation:
To find slope use the equation 
1. Pick any two coordinate pairs to use in the equation. I'll choose (-2, 7) and (-1, 4).
2. Plug these coordinates into the formula. <em>4 - 7 / -1 - - 2</em>
3. Solve!<em> -3/ 1 = -3</em>
4. The slope of this line is -3
