Question

how do you write an equation in point-slope form for the line through the given point with the given slope. (10,-9) m=-2

Answer 1

We know \((x_0,y_0)=(10,-9),m=-1\). Just put it into the point slope formula.\[
y-y_0=m(x-x_0)
\]

Answer 2

Another thing you can do is: \[
y_0=mx_0+b
\]Solve for \(b\), and put it (along with \(m\)) back into \[
y=mx+b
\]

Answer 3

so.. y-(-9) =-1(x-10)?

Answer 4

\(m=-2, m\neq -1\)
You need to simplify as well.
