Answer:
B. -4
Step-by-step explanation:
To find the slope you can count the difference between the 2 points. Slope is rise over run. This means that slope is equal to change in y/ change in x. In this case, the 2 y-values are 8 and -4. This is a decrease of 12, aka -12. Then, the 2 x-values are -1 and 2. This is an increase of 3. Therefore the slope is -12/3. When simplified this equals -4.
Additionally, there is a slope formula, . If you plug in the values, you will get the same answer as the technique above.
The answer it -2

Heya! Princess Kimmie
Let the Direct Variation Equation of Given Ordered pairs be : y = nx
Given : y = 4.8 when x = 4
Substituting the above values in our Equation, we get :
⇒ 4.8 = n × 4
⇒
⇒ The Equation is y = 1.2x
Option 3 is the Answer
Hi!
As you got 108800 you should get it but by x and y.
So can you explain it better so that I can help you!
