Slope intercept form of a line is y=mx+b where m= slope and b=y-intercept.
So, we need to convert the given equation in this form. For that simply solve the equation for y.
x-y=-2
-y=-x-2 Subtract x from each sides.
-y*(-1)=-1*(-x-2) Multily each sides by -1 to isolate y.
y=x+2
So, y=x+2 is the slope intercept form.
Next step is to compare this equation with y=mx+b. After comparing we will get m=1 and b=2
So, slope=1 and y-intercept=2
