Question

Graph a line that is parallel to the given line. Determine the slope of the given line and the one you graphed in simplest form. Click and drag on the graph to draw a line.

Answer 1

Slope = Undefined

Explanation:

The slope of a vertical line does not have a horizontal change. If there is no horizontal change, it is assumed that the number the line is crossing on the x-axis is being divided by 0. Since you can't divide any number by 0, the slope is therefore undefined.

Now, to make a parallel line from a given line, the slope must be the same. Therefore, in this case, you can make another vertical line next to the given line.

In conclusion, both the slopes are undefined, and to make a parallel line, simply follow this rule:

Same slope, different y-intercept.
