1. Module 5 Topic 1 Applications of Linear Functions As x goes up 3, y goes up 1 Direct Variation y=kx

2. There are 2 links that will help you with Direct Variation. The main thing to know is that the formula for Direct Variation is… y=kx K is just the slope of the line, but it is referred to as the constant of variation. It is HOW two things are related. Like, the more you study the higher your grade will be. The “k” tells you how much higher the grade will be.
