Compare the steepness of the lines whose equations are 8x + y = 1 and -8x + y = 2. explain your reasoning.

[10 points, algebra 2]according to my answer key the restrictions are -1 and 4. but why not positive 1?

Solve 3x-18=2y and 5x-6y=14 by elimination or substitution . show all !

Which of the expressions (on the photo document i inserted) together represent all solutions to the following equation? 8cos(12x)+4=-4 *the answer should be in degrees.* > i would like for someone to explain the process to find the solutions for this.
