Answer:

y = \frac{3}{4} x

Step-by-step explanation:

Given that the quantities vary directly then the equation relating them is

y = kx ← k is the constant of variation

To find k use either of the 2 given points

Using (12, 9), that is x = 12 when y = 9, then

k = \frac{y}{x} = \frac{9}{12} = \frac{3}{4}

y = \frac{3}{4} x ← equation of variation

X^2/81 + y^2/64 = 1 The major intercepts are at (±9, 0) (±8, 0) (0, ±9)
Inessa [10]

Answer:

Step-by-step explanation:

Your question is unclear. What are "major intercepts"?

x²/81 + y²/64 = 1

The major axis is horizontal.

0²/81 + y²/64 = 1

y-intercepts = ±8

x²/81 + 0/64 = 1

x-intercepts = ±9
