how do I graph a line when I have the slope and only x coordinates? Ex. Slope of 8, with points (0.5,y), (1,y),(2,y),(3,y) is that even possible or am I reading the problem wrong??

Question

amistre64 · Answer

(1,y )  (2,y)
-1-y  -1-y
-----------
0,0     1,0;  you cant, unless you means each y is different

amistre64 · Answer

then it would be

(1,f(1))    (2,f(2))
-1-f(1)  -1-f(1)
--------------
    0         1,f(1)-f(2) = slope, y/x

f(1)-f(2) = 8

without knowing the actual function that relates x to y, there isnt a way that i can see

amistre64 · Answer

(1,0) (2,8)  is just as valid as (1,23) (2,31)

anonymous · Answer

all the y points are supposed to be different :S

you need at least one instance of an initial condition

thats what I thought but that's all the problem gives me

amistre64 · Answer

(0.5,f(1)-4)

(1,f(1))

(2,f(1)+8)

(3,f(1)+16)

anonymous · Answer

you that the slope$$= \tan \theta$$where $$\theta$$ = the positive angle  between the line and the x axis.
here$$\tan \theta =8 $$
=> $$\theta =\tan^{-1} 8$$
so draw a line making an angle so...........
and then adjust it in such a way that he x coordinates satisfy the line

dhash, there are infinte solutions without knowing how x affects y

how can we locate a y intercept when there is no relation to associate with it?

i guess it's just my textbook being stupid again ill have to talk to my teacher

thanks both of you for trying tho
