Question

What is the slope of the line that passes through the points (14, 5) and (20, –4)?

Answer 1

Use the slope formula :

Answer 2

\(\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
&({\color{red}{ 14}}\quad ,&{\color{blue}{ 5}})\quad &({\color{red}{ 20}}\quad ,&{\color{blue}{ -4}})
\end{array}
\\\quad \\

slope = {\color{green}{ m}}= \cfrac{rise}{run} \implies \cfrac{{\color{blue}{ y_2}}-{\color{blue}{ y_1}}}{{\color{red}{ x_2}}-{\color{red}{ x_1}}}\)

Answer 3

Use the slope formula first:
\[\LARGE m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\]
Then point slope:
\[\LARGE y-y_{1}=m(x-x_{1}\]

Answer 4

Lost a bracket there o:

Answer 5

M=(20-14)/(-4-5)

Answer 6

So it would be -3/2

Answer 7

-2/3? because -6/9

Answer 8

Thanks for your guys' help! It was -3/2

Answer 9

Nevermind me then D:
