Well for a line to be perpendicular to another the slope should be an opposite reciprocal, which in this case is -6/7. One example is y= -6/7x+2
I'm doing interval notations right now in pre-calculus, this how this notation should be written, (-∞,-2] or [4,∞), but this, (x ≤ -2] or [4 ≤ x), means the same thing. closed circle gets a bracket and an open circle gets a parenthesis, infinity always gets a parentheses because it is not a number. hope this helps
