Best ResponseYou've already chosen the best response.1Slope of Perpendicular lines = opposite reciprocal ex: Slope of original line = a/b Slope of perpendicular line = b/a So what would the slope be in the new line?

Best ResponseYou've already chosen the best response.1Okay , you want a line perpendicular to y=2x17. The slope of y=2x17 is 2 or 2/1. Remember the SlopeIntercept form; y = mx + b where m = slope. What is the opposite reciprocal of 2/1? ex: Opposite reciprocal of a/b is b/a

Best ResponseYou've already chosen the best response.12/1 would change into (1/2). So that leaves you with options b and c.

Best ResponseYou've already chosen the best response.1hay one more question if the 0 is on the bottom like 7/0 is it undefined or 0?

Best ResponseYou've already chosen the best response.1It is undefined. Remember rise/run. In this case the line doesn't "run"... It only goes straight up and down, "rises". Vertical line... Slope = undefined Horizontal line... Slope = 0
