Question

The slope of the graph of a direct variation function is 4. What is the equation of the function?

y =1/4 x
y = 4x + 1
y = -4x
y = 4x

Answer 1

y = 4x

Explanation:

A direct variation has NO number added or subtracted like the b in

y = mx + b

The m is the slope which was given.

y = 4x
