Find the x and y Intercepts 3x+6y=18

$3 x + 6 y = 18$

Step 1

Find the x-intercepts.

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

$3 x + 6 (0) = 18$

Solve the equation.

Simplify $3 x + 6 (0)$ .

Multiply $6$ 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 $y$ .

$3 (0) + 6 y = 18$

Solve the equation.

Simplify $3 (0) + 6 y$ .

Multiply $3$ by $0$ .

$0 + 6 y = 18$

Add $0$ and $6 y$ .

$6 y = 18$

Divide each term in $6 y = 18$ by $6$ and simplify.

Divide each term in $6 y = 18$ by $6$ .

$\frac{6 y}{6} = \frac{18}{6}$

Simplify the left side.

Cancel the common factor of $6$ .

Cancel the common factor.

$\frac{6 y}{6} = \frac{18}{6}$

Divide $y$ by $1$ .

$y = \frac{18}{6}$

Simplify the right side.

Divide $18$ by $6$ .

$y = 3$

y-intercept(s) in point form.

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

Step 3

List the intersections.

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

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

Step 4

Find the x and y Intercepts 3x+6y=18
