Write the direct variation equation for the following ordered pairs: {(-12, 3), (-8, 2), (0, 0), (4, -1)}
Recall that the direct variation equation has the form y = kx, where k is the constant of variation. We can find the value of k by using any of the given points.
Let's use the point (0, 0):
0 = k * 0
Since any number multiplied by 0 is always 0, we can say that k can be any value. Therefore, the direct variation equation is y = kx, where k is any real number.
