Write an equation in slope-intercept form of the line with the given slope and point: slope = 3 and (1, -2).

Question

bahrom7893 · Answer

okay you know the slope, but you don't know the intercept

bahrom7893 · Answer

M = slope = (y-y1)/(x-x1)

anonymous · Answer

Ok. So would it be 3x-2

bahrom7893 · Answer

darn it i was doing it right...

bahrom7893 · Answer

nevermind, im having a long day already

anonymous · Answer

haha  xD

bahrom7893 · Answer

M = slope = (y-y1)/(x-x1)
3 = (-2-y1)/(1-x1)

anonymous · Answer

y=3x+1 ?

bahrom7893 · Answer

okay im being retarded here. There's obviously an easy way. Final attempt at solution. If I'm wrong I'll leave this question, very embarrassed

bahrom7893 · Answer

Slope intercept form: y=mx+b

bahrom7893 · Answer

(1, -2); y=-2, x=1, slope = m = 3

bahrom7893 · Answer

-2 = 3*1+b

bahrom7893 · Answer

b = -2-3 = -5
y = 3x - 5

Yea my first solution was correct.. ><
