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

Where:
m: It's the slope
b: It is the cutoff point with the y axis
We find the slope with the given points:

Thus, the line is given by:

We substitute a point to find "b":

Finally, the equation is:

Answer:
