Notice that, in more complicated words but the problem is asking for the equation of the given line.
Recall that to determine the equation of a line, we only need to points on the line and we can use the following formula:
[tex]y_{}-y_1=\frac{y_1-y_2}{x_1-x_2}(x-x_1),[/tex]
where (x₁,y₁) and (x₂,y₂) are points on the line.
Now, notice that the given line passes through (0,0) and (1,8). Substituting these points in the above formula, we get:
[tex]y-0=\frac{8-0}{1-0}(x-0)\text{.}[/tex]
Simplifying the above result we get:
[tex]y=8x\text{.}[/tex]
Finally, exchanging y with c, and x with s, we get:
[tex]c=8s\text{.}[/tex]
Answer:
[tex]r=8.[/tex]
Equation:
[tex]c=8s\text{.}[/tex]
