exoticinspirit · Answer

hey i am exo and im here to help you

anonymous · Answer

sweet thanks

exoticinspirit · Answer

Do you know the slope formula? y=mx+b

anonymous · Answer

no

exoticinspirit · Answer

thats not good you should know it in order to solve your problem. Well in this formula mx is the slope and b is the y- intercept . Using those coordinates plug them in the equation

anonymous · Answer

i dont know how to find slope or y intercept

exoticinspirit · Answer

I understand . to find the slope you do rise/run or change in y over change in x and the y-intercept is just the y axis on the coordinate

anonymous · Answer

im still confused about slope

exoticinspirit · Answer

ok (1,-3) and (3,-5) you have to find the rise over run by subtracting Y2-Y1 over X2-X1 and that equals your slope

anonymous · Answer

ok so 1 and 3 are y2 and y1?

exoticinspirit · Answer

3 is y intercept # 2 and 1 is y- intercept #1

exoticinspirit · Answer

oh wait no thats x1 and x2 my bad

exoticinspirit · Answer

the y-coordinate is on the right

anonymous · Answer

so -3 and -5 are y1 and y2?

exoticinspirit · Answer

-5 is y intercept # 2 and -3 is y #1

anonymous · Answer

ok got it

anonymous · Answer

so 1 and 3 are x1 and x2?

exoticinspirit · Answer

yep show me your answer when youre done :D

anonymous · Answer

how would i solve -3-5/13?

exoticinspirit · Answer

what howd u get that o.e ok it should look like this |dw:1431359399086:dw|
