5-5: Direct Variation. What’s Direct Variation? Direct variation is a function where y = kx, where k ≠ 0 The variables y and x are vary directly with.
Solve. Exercise 5 = 3x x = 5353 5353. 4 = k 1313 1313 Solve. k = 12 Exercise.
Direct variation If Y divided by X always gives you the same number then it is direct variation. I remember this because direct and divide by.
