Answer:

y = -1

Step-by-step explanation:

The slope-intercept form of the equation of a line has the form:

y = mx + b

Where m is the slope and b is the y-intercept.

The slope can be calculated as:


m=(y_2-y_1)/(x_2-x_1)

Where (x1, y1) and (x2, y2) are the coordinates of two points in the line.

So, replacing (x1, y1) by (1, -1) and (x2, y2) by (2, -1), we get:


m=(-1-(-1))/(2-1)=(-1+1)/(1)=(0)/(1)=0

On the other hand, the y-intercept is the point where the line crosses the y-axis. So, the y-intercept is -1.

Finally, the equation of the line in the slope-intercept form is:

y = 0x - 1

y = -1

So, the answer is y = -1
