find the slope.. please help me.?

Favorite Answer

slope (m) = increase in y / increase in x

m = (4 - 9) / (2 + 5) = -5 / 7


m = - 5/7

Any line perpendicular to this line would have slope of 7/5

Since multiplication of slope of 2 perpendicular lines equal -1


Using one of the point (2,4),

(y - 4) / (x - 2) = 7 / 5

5y - 20 = 7x -14

5y = 7x + 6 is the line perpendicular to that point

slope (m) = (y2-y1)/(x2-x1)

(9-4)/(-5-2)
m = 5/-7
to find perpendicular bisector all you do is find the negative reciprocal, or 7/5...Show more

use this equation: y(2)-y(1)/x(2)-x(1) and plug in the numbers from the two points:

y(2)=9
y(1)=4
x(1)=-5
x(2)=2

your equation should look like 9-4/2-(-5)...Show more
