This is not a function. To be a function, there must be a one to one relationship between the independent variable (usually represented by the horizontal or x axis) and the dependent variable (usually represented by the vertical or y axis). A line with undefined slope is a vertical line, so there are an infinite number of possibilities for y and only one possible value of x, so this is not a function.

Graph the line passing through the point -2 4 with slope undefined?
If the slope is undefined, then its a vertical line (up and down) .So draw a vertical line (up and down) that goes through -2 on the x-axis.
How can you tell if a slope is zero or undefined?
A slope is 0 if it is a straight horizontal line. A slope is undefined if it is a straight vertical line.
What lines always have an undefined slope.?
Vertical lines always have an undefined slope. Slope for y = f(x) is given by :slope = dy/dxdx is zero at any point along a vertical line, making the slope undefined along a vertical line.
A horizontal line has a rise which is?
The slope is 0. If it were vertical, the slope would be undefined. APEX ZERO
What is the slope of a vertical line?
Good question. They have infinite slopes. Incidentally, vertical lines are not functions in the formal sense. One x value is mapped on to an infinite number of y values. A function requires that each x maps on to only one y value.
