Equations of linear graphs — practice question

A coordinate plane is displayed with a straight line marked $L$. The x-axis runs from $-4$ to $6$, and the y-axis runs from $-2$ to $5$.

(a)[2]

Find the equation of line $L$, expressed in the form $y = mx + c$.

(b)[1]

Find the equation of the line that is parallel to $y = 3x - 5$ and passes through the point $(0, 17)$.
