Question: Variable Slope

Comment on Variable Slope


I learned before a faster way to get the slope AS LONG AS X and Y ON THE SAME SIDE OF THE EQUATION.. The slope in this question would simply equals -x coefficient /y coefficient SO it will be in this case -a/b. Is this a valid approach? Thanks!

Yes, that's a valid approach.
We actually derive that in the video solution.

Hi Mr Hanneson,
is there any video lecture of coordinate geometry regarding line equations with inequalities. as I am also referring the official guide to GRE with your lectures I came across inequalities equations in graph and line.

THANK YOU

That question type is extremely rare on the GRE. That said, once you know how to graph a line of an equation, it's just a small step to graphing the related inequality.

Cheers,
Brent
