Write the equation of the line and draw the graph of the line through each pair of points given. Use either the slope-intercept equation or by using x- and y-intercepts (3, 5) and (3, 8)

Question

Do you know how to write the slope of the line given two points?

anonymous · Answer

i do not..

mathteacher1729 · Answer

Ok. That would be a good starting point. :) 
 lemmie draw a picture...

awesome :)

mathteacher1729 · Answer

Did that help?
Sometimes it helps to see more than one example, this is a case where the slope is undefined.

anonymous · Answer

a little..i dont know if you saw my last post but im suppose to plot the points and draw a line through the given points then write the equation..

mathteacher1729 · Answer

Right, second picture coming up...

mathteacher1729 · Answer

Let me know if this makes sense. Sorry for my awful handwriting. :-p

anonymous · Answer

cool..so the equation is just x=3..no more work to be done the the problem?

mathteacher1729 · Answer

Yuppers. Slope = undefined , y intercept = doesn't exist. (because it's a straight line up and down that never intesects the y axis. It's just "x = 3".

aaah thank you so much mathteacher! =)
