Question

find the slope of the line through the pair of point (-1/4,1/3) and (-1/2,0)
fractions confuse me help please

Answer 1

Ok, so do you recall the formula that I gave you?

Answer 2

yes but with fractions how would i simplify \[\frac{0+(-1/2) }{1/3+(-1/4) }=\]

Answer 3

to find slope (m) ,
let point be (x1,y1) and (x2,y2)
then slope, m =y2-y1/x2-x1 or y1-y2/x1-x2
m=(0-(1/3))/((-1/2)-(-1/4))

Answer 4

you are not suppsed to add the coordinates .. you have to subtract them.

Answer 5

\[m=\frac{y_2-y_1}{x_2-x_1}\]
So, I get
\[m=\frac{\frac{1}{3}-0}{-\frac{1}{4}-(-\frac{1}{2})}\]

Answer 6

ohhh ok

Answer 7

-2/3

Answer 8

i dont think whhat i got is right

Answer 9

Ok, so the next part is the fraction math.
What is
\[\frac{1}{3}-0\]
and
\[-\frac{1}{4}-(-\frac{1}{2})\]

Answer 10

answer is 4/3

Answer 11

You shouldn't just give answers, you should show them so that they can do it again on their own.

Answer 12

so 1/3-0 would equal to 3 then -1/4-(-1/2)=1/4 and then it would be 4

Answer 13

1/3-0=1/3
the second half is correct at 1/4
so, we now have
\[\frac{\frac{1}{3}}{\frac{1}{4}}\]
how do we solve that?

Answer 14

numberator we have=1/3. your denominator is -1/4-(-1/2) = -1/4+1/2
we an write that as (-1+2)/4=1/4
that is nuthng but 1/3*4

Answer 15

For the final part we would do this
\[\frac{1}{3}\times \frac{4}{1}\]

Answer 16

then we would get 4/3 now i see thank you so much are u a teacher?

Answer 17

Fractal division is merely multiplying by the reciprocal of the denominator.
And no I'm not a teacher, I am a freshman college student.

Answer 18

ur good a math i such

Answer 19

suck

Answer 20

It just takes practice, and lots of it. If you do these problems enough it becomes second nature. Just keep up the good work.

Answer 21

ok thank you
