12. What is the equation of the line perpendicular to the line y = x – 2 that passes through the point
(4,3)?
y = –4/9 x – 2
y = 9/4 x + 6
y = – 9/4 x + 12
y = – 9/4 x – 12

Best ResponseYou've already chosen the best response.0To find the the perpendicular line of y = x – 2, first we should start with the slope. The slope of the first equation is x. The slope of an equation perpendicular to the original will have the opposite reciprocal of the original slope. So we take the reciprical of x which is 1/x. The opposite (or negative) of 1/x would be 1/x. Make sense so far?

Best ResponseYou've already chosen the best response.0Thats how you find the slope right? Sorry I meant (x1, y1) and (x 2, y 2)

Best ResponseYou've already chosen the best response.0That is how you would find the slope when given to pairs of coordinates. For example, if you were given the coordinates (3,4) and (1,2) \[\frac{ y2y1 }{ x2x1 } \rightarrow \frac{ 42 }{ 31 } \rightarrow \frac{ 2 }{ 2 } =1\] But to find the slope perpendicular to the original slope, you don't have to use the formula.

Best ResponseYou've already chosen the best response.0It's just what I said earlier "the opposite reciprocal". That's it. :)
