Write the equation of a
line that has a y-intercept
of -1 and passes through
(-3, 1).

y=-2/3-1

Step-by-step explanation:

To find the slope of a line we need two coordinates on the line. Any two coordinates will suffice. We are basically measuring the amount of change of the y-coordinate, often known as the rise, divided by the change of the x-coordinate, known the the run. The calculations in finding the slope are simple and involves nothing more than basic subtraction and division.
