Graph g(x)=f(-2/3x)

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

Rewrite the function as an equation.

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

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

Rewrite using the commutative property of multiplication.

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

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

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

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

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

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

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

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

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

Use the slope-intercept form to find the slope and y-intercept.

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

$y = m x + b$

Find the values of $m$ and $b$ using the form $y = m x + b$ .

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

$b = 0$

The slope of the line is the value of $m$ , and the y-intercept is the value of $b$ .

Slope: $- \frac{2}{3}$

y-intercept: $(0, 0)$

Slope: $- \frac{2}{3}$

y-intercept: $(0, 0)$

Any line can be graphed using two points. Select two $x$ values, and plug them into the equation to find the corresponding $y$ values.

Create a table of the $x$ and $y$ values.

$\begin{array}{c} x & y \\ 0 & 0 \\ 1 & - \frac{2 f}{3} \end{array}$

Graph the line using the slope and the y-intercept, or the points.

Slope: $- \frac{2}{3}$

y-intercept: $(0, 0)$

$\begin{array}{c} x & y \\ 0 & 0 \\ 1 & - \frac{2 f}{3} \end{array}$
