Question 307209: can yoU give me an step-by-step way to do slope like...
EX: if you had (4,-6) & (-3,7) how would you do that>?
another
EX: if you just had (5,-7) how would you do that if you trying to geT the x-intercept or the y-inercept?
and also any other ways i didnt give yo u an example for thanks!
_->DONT FORGET STEP-BY-STEP(SO I REALLY KNOW HOW O DO iT LOL.)

# 1


Note: is the first point . So this means that x%5B1%5D=4 and y%5B1%5D=-6.
Also, is the second point . So this means that x%5B2%5D=-3 and y%5B2%5D=7.


m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29 Start with the slope formula.


m=%287--6%29%2F%28-3-4%29 Plug in y%5B2%5D=7, y%5B1%5D=-6, x%5B2%5D=-3, and x%5B1%5D=4


m=%2813%29%2F%28-3-4%29 Subtract -6 from 7 to get 13


m=%2813%29%2F%28-7%29 Subtract 4 from -3 to get -7


m=-13%2F7 Reduce


So the slope of the line that goes through the points and is m=-13%2F7


For #2, you need another point to find the equation of the line to get the x and y intercepts.
