Find the Equation that Relates x and y a=2 and b=1

$a = 2$ and $b = 1$

Step 1

When two variable quantities have a constant ratio, their relationship is called a direct variation. It is said that one variable varies directly as the other. The formula for direct variation is $y = k x$ , where $k$ is the constant of variation.

$y = k x$

Step 2

Solve the equation for $k$ , the constant of variation.

$k = \frac{y}{x}$

Step 3

Use the direct variation model to create the equation.

$y = k x$

Step 4

Substitute the value of $k$ into the direct variation model.

$y = (\frac{y}{x}) \cdot x$

Step 5

Simplify the result to find the direct variation equation.

Always true
