Find the x and y Intercepts 3x+5y=-15

$3 x + 5 y = - 15$

Step 1

Find the x-intercepts.

To find the x-intercept(s), substitute in $0$ for $y$ and solve for $x$ .

$3 x + 5 (0) = - 15$

Solve the equation.

Simplify $3 x + 5 (0)$ .

Multiply $5$ by $0$ .

$3 x + 0 = - 15$

Add $3 x$ and $0$ .

$3 x = - 15$

Divide each term in $3 x = - 15$ by $3$ and simplify.

Divide each term in $3 x = - 15$ by $3$ .

$\frac{3 x}{3} = \frac{- 15}{3}$

Simplify the left side.

Cancel the common factor of $3$ .

Cancel the common factor.

$\frac{3 x}{3} = \frac{- 15}{3}$

Divide $x$ by $1$ .

$x = \frac{- 15}{3}$

Simplify the right side.

Divide $- 15$ by $3$ .

$x = - 5$

x-intercept(s) in point form.

x-intercept(s): $(- 5, 0)$

Step 2

Find the y-intercepts.

To find the y-intercept(s), substitute in $0$ for $x$ and solve for $y$ .

$3 (0) + 5 y = - 15$

Solve the equation.

Simplify $3 (0) + 5 y$ .

Multiply $3$ by $0$ .

$0 + 5 y = - 15$

Add $0$ and $5 y$ .

$5 y = - 15$

Divide each term in $5 y = - 15$ by $5$ and simplify.

Divide each term in $5 y = - 15$ by $5$ .

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

Simplify the left side.

Cancel the common factor of $5$ .

Cancel the common factor.

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

Divide $y$ by $1$ .

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

Simplify the right side.

Divide $- 15$ by $5$ .

$y = - 3$

y-intercept(s) in point form.

y-intercept(s): $(0, - 3)$

Step 3

List the intersections.

x-intercept(s): $(- 5, 0)$

y-intercept(s): $(0, - 3)$

Step 4

Find the x and y Intercepts 3x+5y=-15
