Question 80716
You can start with the slope-intercept form of a linear equationL {{{y = mx+b}}} where: m is the slope and b is the y-intercept.
First find the slope of the line passing through the two given points (3, 10) and (3, -3):
{{{m = (y[2]-y[1])/(x[2]-x[1])}}} Making the appropriate substitutions:
{{{m = (-3-10)/(3-3)}}}
{{{m = -13/0}}} This is undefined so the slope is undefined which means that the line is a vertical line.
The equation of this vertical is therefore:
{{{x = 3}}}
