I believe the GCF of 16 and 24 is 8
4x - 6y = 12...in y = mx + b form, the slope will be in the m position. So lets turn this equation into y = mx + b form.
4x - 6y = 12....subtract 4x from both sides
-6y = -4x + 12...now divide both sides by -6
y = (-4/-6)x + 12/-6
y = 2/3x - 2...y = mx + b.....slope(m) = 2/3 <==
I think it may be a 180 degree angle but I wouldnt trust myself so idk
Since both A and B are squared they can be added normally. So A+B would be
(5x^2)+(-3x^2+6) = 2x^2+6.
Either you can use distributive property or you can add up the numbers in the brackets.
Hopefully that helped! :)
