Find the y-intercept 5x-2y=30

$5 x - 2 y = 30$

Step 1

Rewrite in slope-intercept form.

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

$y = m x + b$

Subtract $5 x$ from both sides of the equation.

$- 2 y = 30 - 5 x$

Divide each term in $- 2 y = 30 - 5 x$ by $- 2$ and simplify.

Divide each term in $- 2 y = 30 - 5 x$ by $- 2$ .

$\frac{- 2 y}{- 2} = \frac{30}{- 2} + \frac{- 5 x}{- 2}$

Simplify the left side.

Cancel the common factor of $- 2$ .

Cancel the common factor.

$\frac{- 2 y}{- 2} = \frac{30}{- 2} + \frac{- 5 x}{- 2}$

Divide $y$ by $1$ .

$y = \frac{30}{- 2} + \frac{- 5 x}{- 2}$

Simplify the right side.

Simplify each term.

Divide $30$ by $- 2$ .

$y = - 15 + \frac{- 5 x}{- 2}$

Dividing two negative values results in a positive value.

$y = - 15 + \frac{5 x}{2}$

Write in $y = m x + b$ form.

Reorder $- 15$ and $\frac{5 x}{2}$ .

$y = \frac{5 x}{2} - 15$

Reorder terms.

$y = \frac{5}{2} x - 15$

Step 2

Using the slope-intercept form, the y-intercept is $- 15$ .

$b = - 15$

Step 3

y-intercept in point form.

$(0, - 15)$
