1) Let's verify whether that's true or not, plugging in that point into the equa
(-4,2)
![\begin{gathered} 2=(-5)/(2)(-4)\text{ -8} \\ 2=10-8 \\ 2=2 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/wwhygab64vcodv1ckhqnixiezkpb3i3va7.png)
Since this is an identity, in other words, the left side is equal to the right side then we can say that's true.
So that's true y=-5/2x-8 is the equation of the line that has in one of its points the y-coordinate y=-8
