We have the equation of the line:
This line is written in slope-point form.
This correspond to a line with slope m = 1 that passes through point (-1.-5).
We can find another point of the line by giving x a value, like x = 4, and calculating the corresponding value of y:
Then we have another point at (4,0).
Then, with these two points (-1,-5) and (4,0), we can graph the line as:
