Question

write an equation of the line, in point-slope form. that passes through the given points. (-2,15) and (9,-18)

Answer 1

\[\LARGE \frac{y_2-y_1}{x_2-x_1}=slope\]

Answer 2

My work \[\left(\begin{matrix}15+18 \\ -2+9\end{matrix}\right)=-\left(\begin{matrix}33 \\ 11\end{matrix}\right)=-\left(\begin{matrix}1 \\ 3\end{matrix}\right)\]

Answer 3

You can divide -33/11 to get a simpler answer :)

Answer 4

-3

Answer 5

Yep :)

Answer 6

the equation would look like y-2=-3(x-15), right?

Answer 7

y-y1=m(x-x1)
y-15=-3(x--2)
y-15=-3(x+2)

Answer 8

I think you get confused between y1 and x1
(x,y) <--always that order

Answer 9

I'll take note of that, thank you again

Answer 10
