A linear equation with an undefined slope is an equation where, when graphed, forms a vertical line. For example: when given 2 points: (2, 4) (2,7) ~ The x-values are the same, while the y-values differ, which would create a vertical line when the points are graphed

Because of undefined slope, because undefined slope does not have a slope it doesn't have anything to substitute for m in the point slope equation.
No it is not an undefined slope; the slope of y = -x is -1.The standard form of a linear equation is y = mx + b, where m is the slope, and b is the y-intercept. In y = -x, the y-intercept is 0, and the slope is -1.
Any vertical line has an undefined slope. The equation of the vertical line is x = a where the x-intercept is a.
you say undefined
You can graph a linear equation slope intercept by solving the equation and plugging in the numbers : y=mx+b
