What are the equation and slope of the line that is parallel to the y-axis and goes through the point (1, −2)?

Answer 1

Each point (coordinate) has an ( x, y ). In this example x = 1 and y = -2.

The point slope equation is y = mx + b where m(x) is the slope and b is the y intercept (axis).

So, the equation now is y = m(1) + (-2) or y = m - 2

Slope = 1

Y axis = -2
