Question

Write the equation of the line with an undefined slope, passing through the point (2, 5).

Answer 1

point slope form

Answer 2

y-y0 = m(x-x0)

Answer 3

that doesnt help me

Answer 4

that's because apparently you haven't been learning from previous problems. this is the 3rd or 4th problem with the same type of conditions...

Answer 5

it doesnt help me...and i work them out and get totally different anwser then from what you get.

Answer 6

just compare examples in the book that give you point slope form, and look at how the graph is constructed. 2 points make a line right?

Answer 7

ok, write out what you have... we'll see if they're right...

Answer 8

x= 2 is all i get...so i guess it would be x=2-y?

Answer 9

no, x=2 is your answer...

Answer 10

well then idk what im doing wrong

Answer 11

whenever you have undefined slope, that is a vertical line. there is no y in your equation.

Answer 12

so then is just 2

Answer 13

think about it, there is no way you can get slope from a vertical line. RISE over RUN? theres no run for a line that just goes straight up, in fact it is 0 RUN. what happens when you divide by 0? you cant

Answer 14

you need an equation... x=2 is the equation of the vertical line.

Answer 15

@babacusazn , good point...:)

Answer 16

so is that it then ? is that the answer? yea you have a o. thats just a o....so

Answer 17

5x=2? is that the answer?

Answer 18

draw the point (2,5) the location of that point is at position 2 away from the origin on the x axis and 5 up from the y axis. the only thing that could pass through that point with the aforementioned undefined slope is a vertical line. where does that vertical line pass through?

Answer 19

that doesnt help me....is the answer 5x=2? because that all im getting i dont understand what you are saying...nor do i understand rise over run....

Answer 20

is that where the point is located?
