Question

WILL MARK BRAINLIEST!!!
Line m passes through the points (-4, 3) and (-4, 7). What is the slope of the line that is parallel to line m? Show all of your work for full credit.

Answer 1

The slope of this line is found by
.. m = (change in y)/(change in x)
.. = (7 -3)/(-4 -(-4))
.. = 4/0
.. = undefined

Any line parallel to this line will also have "undefined" slope. (It will be a vertical line, x = constant.)
