Question 56633This question is from textbook Beginning Algebra
: Can someone help me on this problem?
I need to write the equation of the line passing through each pairs of points. I need to write the result in slope-intercept form, where possible.
(2, -3) and (2, 4)
Thanks, Ashley

You can put this solution on YOUR website! Hi Ashley,
(2, -3) and (2, 4)
Did you notice that the x's are the same in both points? If you plotted them and connected the points you'd have a vertical line going through x=2. The equation of a vertical line going through x=2 is  .
:
If you didn't recognize that, try to find the slope using the slope formula: 
(x1,y1)=(2,-3) and (x2,y2)=(2,4)
 0 UNder the bridge=UNdefined is a cool way of remembering that when 0 is in the denominator the fraction is undefined.
Only vertical lines have undefined slopes, and vertical lines are  , where k is some constant.
You can't write this kind of line in slope intercept form, it is a special case:
x=2
Happy Calculating, Ashley!!!
