How much less than 3x^2−7x+9 is 2x^2+4x−8 ?<br> Thanks!!

Simplify.
3x^2−7x+9 - 2x^2+4x−8

1. 3x^2-2x^2 = x
2. -7x + 4x = -3x
3. 9 - 8 = 1

Combine.
x -3x +1

Thus, 2x^2+4x−8 is x -3x +1 less than 3x^2−7x+9

What is the equation of the line with a slope of -1/2 that passes through the point (6,-6)?

m_a_m_a [10]

$y=mx+b \\ \\
\hbox{the slope } m=-\frac{1}{2} \\ \\
y=-\frac{1}{2}x+b \\
(x,y)=(6,-6) \\
-6=-\frac{1}{2} \times 6+b \\
-6=-3+b \ \ \ |+3 \\
b=-3
\\ \\
\boxed{y=-\frac{1}{2}x-3}$
