Question

Tell me what I'm doing wrong
Write the standard from of the equation of the line through the given points: (0,4) and (-1,-1)
\[m=\frac{-1-0}{-1-4}=\frac{1}{5}\]
\[b=y-mx=4-(\frac15)(0)=4\]
\[y=\frac15 x+4\]
\[x-5y=-20\]

Answer 1

@Callisto

Answer 2

m is (y2-y1)/(x2-x1)
You wrote m as (x2-x1)/(y2-y1)
Careful!

Answer 3

oh my....Yeah that makes sense

Answer 4

so in this case,
m = (-1-4) / (-1-0) = -5/-1=5

Answer 5

Yep, very true
Thanks =D
