Step 1.1

The slope-intercept form is $y = m x + b$ , where $m$ is the slope and $b$ is the y-intercept.

$y = m x + b$

Step 1.2

Subtract $6 x$ from both sides of the equation.

$- 2 y = 5 - 6 x$

Step 1.3.3.1.2.2.1

Factor $- 2$ out of $- 2$ .

$y = - \frac{5}{2} + \frac{- 2 (3 x)}{- 2 (1)}$

Step 1.3.3.1.2.2.2

Cancel the common factor.

$y = - \frac{5}{2} + \frac{- 2 (3 x)}{- 2 \cdot 1}$

Step 1.3.3.1.2.2.3

Rewrite the expression.

$y = - \frac{5}{2} + \frac{3 x}{1}$

Step 1.3.3.1.2.2.4

Divide $3 x$ by $1$ .

$y = - \frac{5}{2} + 3 x$

Step 1.4

Reorder $- \frac{5}{2}$ and $3 x$ .

$y = 3 x - \frac{5}{2}$

Step 2

Using the slope-intercept form, the y-intercept is $- \frac{5}{2}$ .

$b = - \frac{5}{2}$

Step 3

y-intercept in point form.

$(0, - \frac{5}{2})$
