Question

Use the slope formula to find the missing coordinate. m=-7/2, T(13,2), W(_, -5)

Answer 1

Hi there :)
Welcome to Openstudy! :~)
Here we use the slope formula which is:
\[ \huge~\rm~\bf\color{blue}{ \frac{y_2-y_1}{x_2-x_1}=slope} \]
We are given several values so let's plug them in :)
\[ \huge~\rm~\bf\color{blue}{ \frac{-5-2}{?-13}=\frac{-7}{2}} \]

Answer 2

We know -5-2=-7
So
What minus 13 equals 2?

Answer 3

You can figure this out by doing the opposite of subtract, which is addition :)
13+2=?

Answer 4

15

Answer 5

Good so out missing value is....?

Answer 6

15

Answer 7

Good :)

Answer 8

Thank you so much

Answer 9

You're welcome :-)
