Question

find the ratio in which the line 2 X + 3 Y - 5 = 0 divides the line segment joining the points(8,-9) and (2,1) also find the coordinates of the point of division

Answer 1

Answer:

−32

Explanation:

2x−3y−5=0

first rearrange to the form

y=mx+c

2x−5=3y

∴y=23x−53

now m= the slope/grdient

⇒m=23

for teh perpendicular slope we use teh relation

m1m2=−1

∴m2=−1m1=−123=−32
