Question 122874
What is the x-intercept?



Let's say (for example) that the x-intercept is (-2,0)



If you want to find the equation of line with an undefined slope which goes through the point ({{{-2}}},{{{0}}}), simply draw a vertical line through {{{x=-2}}}:


{{{drawing(500, 500, -11, 7, -9, 9,
graph(500, 500, -11, 7, -9, 9,0),
line(-2,-20,-2,20)
) }}} Graph of {{{x=-2}}}


So this simply means that the equation of the line is {{{x=-2}}} (notice y is not in the equation. So this means this equation is <font size="4"><b>not</b></font> in slope-intercept form)
