Answer 1

I can help give me a sec :)

Answer 2

well, you have two points there, use them then \(\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({\color{red}{ 4}}\quad ,&{\color{blue}{ 8}})\quad
% (c,d)
&({\color{red}{ 4}}\quad ,&{\color{blue}{ 3}})
\end{array}
\\\quad \\
% slope = m
slope = {\color{green}{ m}}= \cfrac{rise}{run} \implies
\cfrac{{\color{blue}{ y_2}}-{\color{blue}{ y_1}}}{{\color{red}{ x_2}}-{\color{red}{ x_1}}}\)

Answer 3

So for this problem you need to use the slope formula where slope = m
\[m = \frac{ y _{2} - y _{1} }{x _{2} - x _{1} }\]

Now the points on the graph can help, all we need to do is substitute
\[x _{1} = 4\]
\[y _{1} = 8\]
\[x _{2} = 4\]
\[x _{2} = 3\]

It'll look this
\[m = \frac{ 3 - 8 }{ 4 - 4 }\]

Answer 4

From there you can solve

Answer 5

So what should be the answer?
