Since the question does not give us the two points, we will assume those values as shown below:
[tex]\begin{gathered} (x_1,y_1)=(2,4) \\ (x_2,y_2)=(5,0) \end{gathered}[/tex]We proceed to calculate the slope:
[tex]\begin{gathered} slope(m)=\frac{y_2-y_1}{x_2-x_1}=\frac{0-4}{5-2}=-\frac{4}{3} \\ slope(m)=-\frac{4}{3} \end{gathered}[/tex]The next step is to use the point-slope equation to solve for the equation:
[tex]\begin{gathered} y-y_1=m(x-x_1) \\ (x_{1,}y_1)=(2,4) \\ y-4=-\frac{4}{3}(x-2) \\ y=-\frac{4}{3}x+\frac{8}{3}+4\Rightarrow y=-\frac{4}{3}x+\frac{20}{3} \\ y=-\frac{4}{3}x+\frac{20}{3} \end{gathered}[/tex]
