Slope is -1 and (2,1) is on the line the equation of the line is?

Part a : solve -vp + 40 < 65 for v part b : solve 7w - 3r = 15 for r show your work .

Use the graph to determine the range. which notations accurately represent the range? check all that apply. (–∞, 2) u (2, ∞) (–∞, –2) u (–2, ∞) {y|y ∈ r, y ≠ –2} {y|y ∈ r, y ≠ 2} y < 2 or y > 2 y < –2 or y > –2

If a || b and b | y, then ? a) x || y. b) x | a. c) a | y. d) a || y.
