Suppose y varies directly with x and when y=10 when x=-3. What direct variation equation relates x and y? What is the value of y when x = - 1?

Suppose y varies directly as x, and y=-65 when x=-26. Write a direct variation equation that relates x and y.

.

If "y varies directly as x" it is in the form of:

y = kx

where k is a constant

.

Using the values provided, you can find k.

y = kx

-65 = k (-26)

-65 / (-26) = k

2.5 = k

.

So, our equation is:

y = 2.5x
