Let's first find the slope
To find the slope you can use any two points in the table. The following are the two I picked:
(-3, 18) and (0, 12)
The formula for slope is
[tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
In this case...
[tex]y_{2} =12\\y_{1} =18\\x_{2} =0\\x_{1} =-3[/tex]
^^^Plug these numbers into the formula for slope...
[tex]\frac{12 - 18}{0 - (-3)}[/tex]
[tex]\frac{-6}{3}[/tex]
Simplify to...
-2
^^^This is your slope
Y-intercept is where the graph intersect with the y axis, which makes the x value 0. This means that the coordinate should look like so...
(0, y)
In this case the y-intercept is:
(0, 12)
Your answer is B!
Hope this helped!
