Find the x and y Intercepts 3x+2y=-18

$3 x + 2 y = - 18$

Step 1

Find the x-intercepts.

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

$3 x + 2 (0) = - 18$

Solve the equation.

Simplify $3 x + 2 (0)$ .

Multiply $2$ by $0$ .

$3 x + 0 = - 18$

Add $3 x$ and $0$ .

$3 x = - 18$

Divide each term in $3 x = - 18$ by $3$ and simplify.

Divide each term in $3 x = - 18$ by $3$ .

$\frac{3 x}{3} = \frac{- 18}{3}$

Simplify the left side.

Cancel the common factor of $3$ .

Cancel the common factor.

$\frac{3 x}{3} = \frac{- 18}{3}$

Divide $x$ by $1$ .

$x = \frac{- 18}{3}$

Simplify the right side.

Divide $- 18$ by $3$ .

$x = - 6$

x-intercept(s) in point form.

x-intercept(s): $(- 6, 0)$

Step 2

Find the y-intercepts.

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

$3 (0) + 2 y = - 18$

Solve the equation.

Simplify $3 (0) + 2 y$ .

Multiply $3$ by $0$ .

$0 + 2 y = - 18$

Add $0$ and $2 y$ .

$2 y = - 18$

Divide each term in $2 y = - 18$ by $2$ and simplify.

Divide each term in $2 y = - 18$ by $2$ .

$\frac{2 y}{2} = \frac{- 18}{2}$

Simplify the left side.

Cancel the common factor of $2$ .

Cancel the common factor.

$\frac{2 y}{2} = \frac{- 18}{2}$

Divide $y$ by $1$ .

$y = \frac{- 18}{2}$

Simplify the right side.

Divide $- 18$ by $2$ .

$y = - 9$

y-intercept(s) in point form.

y-intercept(s): $(0, - 9)$

Step 3

List the intersections.

x-intercept(s): $(- 6, 0)$

y-intercept(s): $(0, - 9)$

Step 4

Find the x and y Intercepts 3x+2y=-18
