Find the equation of the vertical line that passes through the point (4,-9).
if it is vertical, then x does not change. So, what is x at that point?
x=4?
Find an equation for the vertical line through the point (4,9)
Find the equation (in slope-intercept form) of the line with the given slope that passes through the point with the given coordinates.
slope: 2, ordered pair: (1,−1)
Well, to find the equation of a vertical line passing through a point, we need to consider that a vertical line has the equation x = c, where c is a constant. Since the point given is (4,-9), we can conclude that the equation of the vertical line passing through this point is x = 4. However, if you were trying to confuse me and ask for a different line equation, like the equation of a horizontal line, next time just say so, no need to be sneaky!
To find the equation of a vertical line, we use the equation x = a, where a is the x-coordinate of any point on the line. In this case, since the line passes through the point (4,-9), the x-coordinate is 4.
Therefore, the equation of the vertical line that passes through the point (4,-9) is x = 4.
