7 y = k x

$7 y = k x$ ,

m = 2

$m = 2$

Step 1

Divide each term in

Step 1.1

Divide each term in

7 y = k x

$7 y = k x$ by

7

$7$ .

\frac{7 y}{7} = \frac{k x}{7}

$\frac{7 y}{7} = \frac{k x}{7}$

Step 1.2

Step 1.2.1.1

Cancel the common factor.

$\frac{7 y}{7} = \frac{k x}{7}$

Step 1.2.1.2

Divide

$y$ by

$1$ .

$y = \frac{k x}{7}$

$y = \frac{k x}{7}$

$y = \frac{k x}{7}$

$y = \frac{k x}{7}$

Step 2

Find the slope of the equation in terms of

$k$ using the slope-intercept form.

$m = \frac{k}{7}$

Step 3

Set the known value of

$m$ equal to the slope of the equation in terms of

$k$ .

$2 = \frac{k}{7}$

Step 4

Rewrite the equation as

$\frac{k}{7} = 2$ .

$\frac{k}{7} = 2$

Step 5

Multiply both sides of the equation by

$7$ .

$7 \frac{k}{7} = 7 \cdot 2$

Step 6

Simplify both sides of the equation.

Step 6.1.1.1

Cancel the common factor.

$7 \frac{k}{7} = 7 \cdot 2$

Step 6.1.1.2

Rewrite the expression.

$k = 7 \cdot 2$

$k = 7 \cdot 2$

$k = 7 \cdot 2$

Step 6.2

Simplify the right side.
