In advance! the y-intercept of the line whose equation is x - y = -1 is -1, 0, or 1

So to rearrange it in the form of y=Mx+b
x-y=-1
if you shift over the X you get
-y=-x-1
now we want y coefficient to be positive as that's the general form.
divide the whole equation by-1
y=X+1
intercept is 1 then

Move the decimal behind it

a - base

b - exponent

so,

the base is 8the exponent is 3the exponent tells you to multiply 8 together three timesthe expanded form is 8*8*8
