Suppose y varies directly with x.
Write a direct variation equation that relates x and y.
y = -10 when x = 2
(1 point)
The direct variation equation that relates x and y can be written as:
y = kx
To find the value of k, we can plug in the given values of y and x:
-10 = k(2)
To solve for k, divide both sides of the equation by 2:
k = -5
Therefore, the direct variation equation that relates x and y is:
y = -5x
