Complete the point slope equation of the line through (-5, 7) and (-4, 0).

For this case we have that by definition, the point-slope equation of a line is given by:

Where:

m: It's the slope

b: It is the cut-off point with the y axis

We have two points:

We found the slope:

Thus, the equation is of the form:

We substitute one of the points and find "b":

Finally, the equation is:
