The equations that are direct variation functions are; y = x and y = ¹/₄x + 2
Direct Variation function is defined as the function where two quantities vary directly i.e. variables x and y are said to be directly varying if y = kx. Where;
k is the constant of variation.
Thus, from the options, we see that the function,
y = x varies directly with the constant of variation i.e. k = 1.
Similarly, y = ¹/₄x + 2 is also varying directly with constant k=1
Complete Question is;
Which equation is a direct variation function?
y = x
y = 4
y = x²
y = x + 2
y = ¹/₄x + 2
