Simone claims that the slope of the line through (-2,7) and (3,0) is the same as the slope of the line through (2,1) and (12,-13) prove or disprove simone's claim This is one of the questions on my homework, and I do not understand it at all. :(
@dude
@redhead23
@GirlBesty
idk
Do you know how to find the slope between two points?
yeah i am here to answer
only when its on a table. Idk how to make this a table tho.
so im pooped
so all u need to now is how to put it on the table?
but im also not rlly sure if i get it even with the table, im just hoping i do :(
ight i will help with that to well try to anyways
So, label a point as "point 1" and "point 2" For the first set you have (-2,7) and (3,0) (-2,7) is your "point 1" (3,0) is your "point 2" Remember that each point is written as (x,y) First subtract the y values (Second y point - first y point)
slope = (Y2-Y1)/(X2-X1) (0-7)/(3+2) = -7/5 (-13 -1) / (12-2) = -14/10 = -7/5 sure enough
so the y is zero and the x is one?
Careful, subtract only the y points Point 2 (y) minus "point 1" (y)
Sorry y is sevem
@redhead23 Yeah, do you understand what \(y_\#\) and \(x_\#\) are?
Yeah 0 - 7
ok, so what next?
You get -7 Now subtract the x values (Second x point minus first x point) Point 1: (-2,7) Point 2: (3,0)
so 1? or -5?
-5!
well isnt x 2 and y 1 i am not sure tho
wait i am wrong
no bc u r subtracting 3 from -2
so -5
Close Point 1: (-2,7) <- first point x is -2 Point 2: (3,0) <- second point x is 3 Second x minus first would be: \(3 - (- 2)\)
so 1?
Double negative is just positive \(3+2\)
OH RIGHT
5
Now divide the y subtracted and the x subtracted (y subtracted: -7) Earlier (x subtracted: 5) What we just did \(\dfrac{-7}{5}\) or just \(-\dfrac75\)
@redhead23 You were right but make sure you know what you are doing
We dont give out answers
oh sorry so i cant just say the answer i have to go through it and explain it to the person?
im confused what do i do after that
its a fraction, so do i do the same to the other side?
That's it
Now do the same for the other two points
ight my fault bro
and then see if the fractions are equal?
Yes
also i didnt see it redhead so ur good
Thank you dude? im gonna give u a medal, but can u give one to redhead as well?
thank you both!
well thank dude bc he went an explained it to u soo but yw tho
So basically 1. Subtract second y point from the first point 2. Subtract the second x point from the first 3. Divide what you got for the y over the x ~~~ If you're feeling confident the equation can help you \(\dfrac{y_2-y_1}{x_2-x_1}\) The number at the bottom just means which point it comes from Point 1: \((x_1,y_1)\) Point 2: \((x_2,y_2)\)
