Given the equation of a straight line


y=mx+c

m is the slope and c is the intercept on the y axis

From the table in the question, the equation of the line can be obtained using two points form the equation of a straight line


y-y_1=(y_2-y_1)/(x_2-x_1)(x-x_1)

Pick two points on the table and substitute for the x values and y values


(-6,-24)\text{ and (3, -12)}
\begin{gathered} x_1=-6,y_1=-24 \\ x_2=-3,y_2=-12 \end{gathered}
\begin{gathered} m=(y_2-y_1)/(x_2-x_1) \\ m=(-12-(-24))/(-3-(-6))=(-12+24)/(-3+6)=(12)/(3)=4 \end{gathered}
\begin{gathered} y=mx+c \\ -24=4(-6)+c \\ -24=-24+c \\ c=-24+24=0 \end{gathered}

Hence, the equation of the table is y = 4x
