Answer 1

notice the line passes through those 2 points, thus \(\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
&({\color{red}{ 0}}\quad ,&{\color{blue}{ 6}})\quad &({\color{red}{ -3}}\quad ,&{\color{blue}{ 0}})
\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 2

now I just subtract?

Answer 3

subtract and simplify

Answer 4

ok

Answer 5

I got 2 @jdoe0001
