Question

Find an equation of the line that has undefined slope and contains the point left parenthesis negative 1 comma 6 right parenthesis(−1,6). if​ possible, write the equation in​ slope-intercept form. check that the ordered pair that represents the given point satisfies the equation.

Answer 1

When the slope isn't defined, it's not possible to write the line in slope-intercept form. No slope means a vertical line, which here must be

$x= -1$

The ordered pair (-1,6) obviously satisfies the above equation so is on the vertical line $x=-1$.
