Determine whether y varies directly with x. If so find the constant of variation k and write the equation.

There seems to be a direct relationship, as an increase an x results in an increase in y, but we can check if:
y = kx

11 = 7k, k = 1.57
13 = 8k; k = 1.62
15 = 9k; k = 1.67
17 = 10k; k = 1.70

As we can see, the variation is not constant so this is not a simple direct relation.

Answer:

11 = 7k, k = 1.57

13 = 8k; k = 1.62

15 = 9k; k = 1.67

17 = 10k; k = 1.70

Y does not have an direct variation with x.

Two equations are given below: a − 3b = 9 a = b − 3 What is the solution to the set of equations in the form (a, b)? (−9, −6) (−

Anna [14]

To solve this equation you can plug in these numbers into the equations, so for example you can that the equation a-3b=9 and the points are (-9,-6). you would then insert the numbers so you would have the equation (-9)-3(-6)=9. simplify -9+18=9 and there you have it, the answer is (-9,-6)
