Find the equation of the line that contains the point (1,-5) and has a slope that is undefined.

Question

Express the equation using either the general form or the​ slope-intercept form of the equation of a line. The equation of the line is

Answer 1

x= 1 goes through the given point.

"Undefined" slope means a vertical line.

(1,-5) is the point with a line through it, with undefined slope.

in point slope form the equation is

(y-(-5))/(x-1) = m = undefined = a fraction with zero as the denominator

(y+5)/(x-1) has zero in the denominator when x-1 =0 or x=1

Answer 2

x=1

it is a vertical line if the slope is undefined
