QuestionGraph the line through $(-1,-2)$ and $(-1,3)$, find its equation in standard form, and calculate the slope.

Studdy Solution
The slope of a vertical line is undefined because the denominator of the slope formula, which is the difference in the x-coordinates, is zero. The slope formula is $\frac{y2 - y1}{x2 - x1}$, and for a vertical line, $x2 - x1 =0$.
So, the slope of the line is undefined.
The solution to the problem is(a) The line passing through the points $(-1,-2)$ and $(-1,3)$ is a vertical line. (b) The equation of the line in standard form is $x +1 =0$. (c) The slope of the line is undefined.
