First lets define what is the equation of a line:

equation of a line is

y=mx +b

So, equation in slope intercept form would be y=mx +b

To calculate the slope m we would have to use the points (2, -1) and (-3,-1)​ and calculate the following formula:

slope= y2-y1/x2-x1

slope=-1+1/-3-2

slope=0

Therefore, equation in slope intercept form would be for points x -1 and y -1 would be:

-1=0*-1 + b

-1=b

Hence, y= -1
