Chapter 1 - Linear Functions - 1.1 Slopes and Equations of Lines - 1.1 Exercises: 18

Answer

$x=-8$ This equation has no slope-intercept form equivalent.

Work Step by Step

A line with an undefined slope is a vertical line. Vertical lines have equations of the form $x=k$, where $k$ is the x-coordinate of each point on the line. The line passes through the $(-8, 1)$, whose x-coordinate is $-8$. Thus, the equation of the line is $x=-8$. This equation has no slope-intercept form equivalent.
