Question

determine whether this equation represents a direct variation . if it does, find the constant of variation 8x+9=10

Answer 1

The equation 8x+9=10 represents a direct variation, and the constant of variation is 1/8.

Step-by-step explanation:

The equation 8x+9=10 represents a direct variation because it is in the form y=kx, where k is the constant of variation. To find the constant of variation, we need to isolate x on one side of the equation. Subtract 9 from both sides:

8x = 10 - 9

8x = 1

Divide both sides by 8:

x = 1/8

Therefore, the constant of variation is 1/8.
