Rule:
The equation
has slope and
y-intercept the point
Therefore to use that rule, your equation
must first be gotten into the form
Let's do that:
Clear of fractions by multiplying every term by
Add -40 to both sides
Get rid of the negative sign in front of y by changing
the sign of every term on both sides:
Compare that to
and we see that it
has slope and
y-intercept the point
