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

U hv an equation of a line is
y=(4/9)x-2
Right?

Answer 2

Standard equation of a line is
y=mx+c

Answer 3

m=slope

Answer 4

So slope of ur given line=m1=4/9
Right?

Answer 5

Let the slope of ur perpendicular line =m2

Answer 6

So we can write
m1*m2=-1

Answer 7

(4/9)*m2=-1
m2=-9/4

Answer 8

Use
y-y1=m2(x-x1)
