Write an equation of a line with an undefined slope and passing through the point (-2,4). hint: to answer this question, consider the type of line that has an undefined slope. then write an equation of that line using the values in the ordered pair.

We are asked for the equation of the line that passes through (-2,4) and has an undefined slope. An undefined slope means the slope is infinity or that the change in y is zero. Hence, the line should be vertical. The line that passes through (-2,4) is x = -2.
