Find the x and y Intercepts y=-2/3x-3

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

Step 1

Find the x-intercepts.

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

$0 = - \frac{2}{3} x - 3$

Solve the equation.

Rewrite the equation as $- \frac{2}{3} x - 3 = 0$ .

$- \frac{2}{3} x - 3 = 0$

Simplify each term.

Combine $x$ and $\frac{2}{3}$ .

$- \frac{x \cdot 2}{3} - 3 = 0$

Move $2$ to the left of $x$ .

$- \frac{2 x}{3} - 3 = 0$

Add $3$ to both sides of the equation.

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

Multiply both sides of the equation by $- \frac{3}{2}$ .

$- \frac{3}{2} (- \frac{2 x}{3}) = - \frac{3}{2} \cdot 3$

Simplify both sides of the equation.

Simplify the left side.

Simplify $- \frac{3}{2} (- \frac{2 x}{3})$ .

Cancel the common factor of $3$ .

Move the leading negative in $- \frac{3}{2}$ into the numerator.

$\frac{- 3}{2} (- \frac{2 x}{3}) = - \frac{3}{2} \cdot 3$

Move the leading negative in $- \frac{2 x}{3}$ into the numerator.

$\frac{- 3}{2} \cdot \frac{- 2 x}{3} = - \frac{3}{2} \cdot 3$

Factor $3$ out of $- 3$ .

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

Cancel the common factor.

$\frac{3 \cdot - 1}{2} \cdot \frac{- 2 x}{3} = - \frac{3}{2} \cdot 3$

Rewrite the expression.

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

Cancel the common factor of $2$ .

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

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

Cancel the common factor.

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

Rewrite the expression.

$- - x = - \frac{3}{2} \cdot 3$

Multiply.

Multiply $- 1$ by $- 1$ .

$1 x = - \frac{3}{2} \cdot 3$

Multiply $x$ by $1$ .

$x = - \frac{3}{2} \cdot 3$

Simplify the right side.

Simplify $- \frac{3}{2} \cdot 3$ .

Multiply $- \frac{3}{2} \cdot 3$ .

Multiply $3$ by $- 1$ .

$x = - 3 (\frac{3}{2})$

Combine $- 3$ and $\frac{3}{2}$ .

$x = \frac{- 3 \cdot 3}{2}$

Multiply $- 3$ by $3$ .

$x = \frac{- 9}{2}$

Move the negative in front of the fraction.

$x = - \frac{9}{2}$

x-intercept(s) in point form.

x-intercept(s): $(- \frac{9}{2}, 0)$

Step 2

Find the y-intercepts.

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

$y = - \frac{2}{3} \cdot 0 - 3$

Solve the equation.

Remove parentheses.

$y = - \frac{2}{3} \cdot 0 - 3$

Simplify $- \frac{2}{3} \cdot 0 - 3$ .

Multiply $- \frac{2}{3} \cdot 0$ .

Multiply $0$ by $- 1$ .

$y = 0 (\frac{2}{3}) - 3$

Multiply $0$ by $\frac{2}{3}$ .

$y = 0 - 3$

Subtract $3$ from $0$ .

$y = - 3$

y-intercept(s) in point form.

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

Step 3

List the intersections.

x-intercept(s): $(- \frac{9}{2}, 0)$

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

Step 4
