The equation of a line in slope-intercept form with the given slope and $y$ -intercept is $y = 鈭� \frac{5}{8} x 鈭� 2$ .

The graph of the equation $y = 鈭� \frac{5}{8} x 鈭� 2$ is:

Step by step solution

Step 1. Write the slope-intercept form of a line.

The equation of line in slope-intercept form is:

$y = m x + b$

Where $m$ is the slope of the line and $b$ is the $y$ -intercept of the line.

Step 2. Write the equation of a line in slope-intercept form having slope −58 and y-intercept −2.

The slope of the line is $鈭� \frac{5}{8}$ . Therefore, the value of $m$ is $鈭� \frac{5}{8}$ .

The $y$ -intercept of the line is $鈭� 2$ . Therefore, the value of $b$ is $鈭� 2$ .

Now substitute $鈭� \frac{5}{8}$ for $m$ and $鈭� 2$ for $b$ in the equation $y = m x + b$ to find the slope-intercept form of the line.

$y = m x + b = (鈭� \frac{5}{8}) x + (鈭� 2) = 鈭� \frac{5}{8} x 鈭� 2$

Therefore, the equation of a line in slope-intercept form with the given slope and $y$ -intercept is $y = 鈭� \frac{5}{8} x 鈭� 2$ .

Step 3. Draw the graph of the equation y=−58x−2.

The graph of the equation $y = 鈭� \frac{5}{8} x 鈭� 2$ is:
