Maurinko [17]3 years ago
4 0

Answer:

y = - \frac{24}{x}

Step-by-step explanation:

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

y = \frac{k}{x} ← k is the constant of variation

To find k use the condition x = 4 when y = - 6

k = yx = - 6 × 4 = - 24

y = - \frac{24}{x} ← equation of variation

Line z has a slope of 2.5 and goes through point (4, 13). Which equation best represents line z?​
Rus_ich [418]

Answer:

y - 13 = (5/2)(x - 4)

Step-by-step explanation:

Here we know the slope and one point on the line.  Use the point-slope formula:

y - k = m(x - h).

Substituting 13 for k, 4 for x and 2.5 for m, we get:

y - 13 = (5/2)(x - 4)\
