Question

The gran represents the costy (in dollars to open an online gaming account and buy x games. Find the slope and the v-intercept of the Ine.

Answer 1

To find the slope of the line we have to identify two coordinates in the line and use this equation:

`m=(y_2-y_1)/(x_2-x_1)`

So I use the coordiantes (0,15) and (3,45) so

`\begin{gathered} m=(45-15)/(3-0) \\ m=10 \end{gathered}`

and the y intercept is 15 so the general equation will be:

`y=10x+15`
