Answer:

y = - 2x

Step-by-step explanation:

Given that x and y vary directly then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition x = - 5, y = 10

k = [tex]\frac{y}{x}[/tex] = [tex]\frac{10}{-5}[/tex] = - 2

y = - 2x ← equation of variation

The equation that relates x and y will be y=2x.

What is the equation?

A mathematical statement consisting of an equal symbol between two algebraic expressions with the same value is known as an equation.

Given values;

x = -5

y = 10

Divide y by x;

y/x = 10/-5

y/x=-2

y=2x

Hence, the equation that relates x and y will be y=2x.
