Question

Tell whether the equation -x+4y=-2 represents a direct variation. If so, identify the constant of variation.

Answer 1

The equation -x + 4y = -2 represents a direct variation with a constant of variation of 4.

Step-by-step explanation:

The equation -x + 4y = -2 represents a direct variation. A direct variation is a relationship between two variables where a change in one variable leads to a proportional change in the other. In this equation, the constant of variation is 4, which means that for every unit increase in y, x will decrease by 1/4.
