Question

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.

Answer 1

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.
