Use the given x and y values to write a direct variation
equation.
x = 2, y = 30

y = 15x

Step-by-step explanation:

Given x and y are in direct variation then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition x = 2, y = 30, then

30 = 2k ( divide both sides by 2 )

15 = k

y = 15x ← equation of variation

the distance between point a and point b is 6 units

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
