Hi welcome to openstudy :-)
Use the following:
\[\huge y-y_1=m(x-x_1)\]
where
m=slope
(x1,y1)

Im not new just a new account lol but thanks but I dont understand your response
pooja195 (pooja195):
Ok are you fimiliar with the point slope formula?
OpenStudy (anonymous):
Yes and no
pooja195 (pooja195):
What do you mean? What part don't you understand? :-/

I do know about slope
pooja195 (pooja195):
Ok
We have this formula called the point slope formula
\[\huge~\rm~\bf~y-y_1=m(x-x_1)\]
OpenStudy (anonymous):
ok
pooja195 (pooja195):
M is the slope
what is the # of the slope given?
OpenStudy (anonymous):
8,3

m=5
pooja195 (pooja195):
Good :)
\[\huge~\rm~\bf~y-y_1=5(x-x_1)\]
can you tell me what
x=?
y=?
OpenStudy (anonymous):
no
pooja195 (pooja195):
Look at the coordinates
OpenStudy (anonymous):
8,3

Ok
from that which number is x
which is y
OpenStudy (anonymous):
idk
pooja195 (pooja195):
in a coordinate pair we have (x,y)
(8,3) is our coordinate based off of this tell me what x and y are.
OpenStudy (anonymous):
idk tbh
pooja195 (pooja195):
x=8 because it is the first number
y=3 because it is the 2nd number
(x,y) (8,3)
Now all you need to do is plug the numbers into the formula
x1=8
y1=3
