Question

Persamaan garis yg tegak lurus dg garis 5x+2y+10 =0 dan melalui titik (4,3) adalah pake cara ya

Answer 1

5x+2y+10 =0 
7xy+10 =0
17xy=0
xy=170x4,3
xy= itung sendiri 

---------------------

Answer 2

2y = -5x-10
y = -5/2-5

m1 = -5/2
-1 = m1 x m2
-1 = -5/2 x m2
m2 = 2/5

y-y1 = m(x-x1)
y-3 = 2/5 (x-4)
y-3 = 2/5x-8/5
y = 2/5x-8/5+3
y = 2 /5x + 7/5
5y = 2x + 7
5y - 2x - 7 = 0
