Question 1117240: A line l is parallel to the y-axis and passes through the point (2,3). What is its gradient (m) and x-intercept?
m= 0 , x= (3,0)
m= ∞ , x= (2,0)
m= 0 , x= (2,0)
m= ∞ , x= (3,0)
m= 2 , x= (0,0)
how do I figure this out quickly without a graphing calculator?

You can put this solution on YOUR website! parallel lines have the same slope
:
the x-intercept is (2, 0)
:
the equation for the line is
:
x = 2, all points on this line have the same x-coordinate
:
the gradient(slope) tends to infinity
