What is the function rule for the line?

For this case we have that 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 can find the slope using two points that cross the line.

Thus, the equation is of the form:

We substitute a point to find "b":

Finally, the equation is:

answer: a
