Question

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

Answer 1

In Statistical Mathematics the product of the gradients of two lines is -1

Answer 2

Use this :
Y2-Y=m(X2-X)
In there :
X2=4
Y2=3
Got it ?:)

Answer 3

m is slope .
You see that after the x :)
It s 4/9

Answer 4

These are the answer choices I don't see where u are coming from

Answer 5

y = mx + c
Gradient of the line acc to the law i stated = -2.25
y=-2.25x +c
Substituting the co-ordinates
3=-2.25*4 +c
3=-9+c
c=11
Therefore equation of the line is
y=-2.25x + 12

Answer 6

So the third option is correct acc to me What do u think @E.ali

Answer 7

In Statistical Mathematics the product of the gradients of two lines is -1
