Which of the following equations shows a direct variation?
a. y = 5x
b. y=x+1
C. y=x2-1
d. y = 2x - 1​


Sagot :

Answer:

A.

Step-by-step explanation:

A direct variation, also called direct proportion is a relationship between two variables x and y that can be written as y = kx, k ≠ 0. This situation occurs when the ratio of two variables is constant. When y = kx, we say that y varies directly with x.
