There's a standard, much-used formula for the slope of a line connecting 2 given points. Look up "slope" on the 'Net if need be. Apply that formula to the 2 given points. Pls show your work.
OpenStudy (rye2581):
That more so what im looking for the slope intercept form.
OpenStudy (amorfide):
\[m=\frac{ y_{2}-y_{1} }{ x_{2}-x_{1} }\]
where m is the gradient
the y2 y1 x2 x1 represent the values from the coordinates
OpenStudy (rye2581):
I got -7/-17 and slope intercept is y=mx+b ? im so confused I havent done this is so long.
OpenStudy (amorfide):
it is only asking for the slope

yes
OpenStudy (amorfide):
so you don't need slope intercept form
OpenStudy (amorfide):
just use the formula I gave and that is your answer
OpenStudy (rye2581):
perfect thank you so much!
OpenStudy (amorfide):
for the record
-9-2=-11

so you should have
-11/-17
the negative sign cancels
11/17
OpenStudy (rye2581):
I did -9-(-2) and got -7
OpenStudy (amorfide):
your coordinate says (10,2)
that is a positive 2
hence it would be
-9-(2)
