To find the equation of the line we need the slope and the y-intercept

The slope is given by:


m=(y_2-y_1)/(x_2-x_1)

Using the points given we have tha the slope is:


\begin{gathered} m=(-3-1)/(0-(-5)) \\ m=(-4)/(5) \\ m=-(4)/(5) \end{gathered}

The y-intercept is the value of y when x=0; fron the graph we have that b=-3.

Once we have the slope and y-intercept we plug them into the equation; hence the equation we are looking for is:


y=-(4)/(5)x-3
