Yes. For example, the lines x=7, x=-1, and x=145 all have an undefined slope; they are all vertical.

Why is the slope of a graph x equals k where k is some constant undefined?

The Slope is Undefined, the line is vertical


Why can't all linear equations be written using point slope?

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.


Does in linear graphs the slope of the line change with the x coordinate?

In a linear graph the slope is the same everywhere, assuming vertical line graphs are not allowed. Depending on context, a vertical line (say x = 3) is not always allowed. If the graph is a vertical line then the slope is infinite at the single value of x. (That would be 3 in the example above.) The slope would then be undefined elsewhere.


What type of graph has a constant slope?

How do you graph a linear equation slope intercept?

You can graph a linear equation slope intercept by solving the equation and plugging in the numbers : y=mx+b


Does in linear graphs the slope of the line change with the x-coordinate?

No. A linear graph has the same slope anywhere.

What does it mean if the slope of a line is undefined?

it means that the line in the linear equation is a vertical line


How does the graph of an exponential function differ from the graph of a linear function and how is the rate of change different?

The graph of a linear function is a line with a constant slope. The graph of an exponential function is a curve with a non-constant slope. The slope of a given curve at a specified point is the derivative evaluated at that point.


Please help -- How does the slope and y-intercept change if you reverse the x and y axis of a linear graph. Will the graph still be linear?

If it was linear to start with it will still be linear. The slope will change to its reciprocal. The y-intercept will be unchanged (but it will look different)


How do you get a linear equation from a graph?

Slope= rise over run


Is y equals -x an undefined slope?

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.
