1. quick way would be to know that for
Ax + By = C, the slope is -A/B

so for your equation, slope = -10/-5 = 2

or, change your equation to the form y=mx + b, then m is the slope

so...
10x-5y=270
-5y = -10x + 270, now divide both sides by -5
y = 2x - 54, so the slope is 2, as above.

-7+ 5x = 10x-2? im not sure I know its -1, but im not sure how. -7 + 5x = 10x - 2 Since we need to get the unknowns on one side and the knowns on the other side and change their signs: 5x - 10x = 7 - 2 -5x = 5 x = -1 wait how did
