C 2/5
D 5/2

Answer 3

i know the slope is 5/2 but i dont know if it is negative

Answer 4

\[ \huge~\rm~\bf\color{blue}{ \frac{y_2-y_1}{x_2-x_1}=slope} \]
\[ \huge~\rm~\bf\color{blue}{ \frac{10-5}{-7--9}=slope} \]
\[ \huge~\rm~\bf\color{blue}{ \frac{10-5}{-7+9}=slope} \]
\[ \huge~\rm~\bf\color{blue}{ \frac{10-5=5}{-7+9=2}=slope} \]
It would remain positive -7+9=2 so there would be no reason for the slope to be negative

Answer 5

So basically there is no reason to put negative

Answer 6

ok ty
