Write an equation in standard form perpendicular to 4x-3y=12 through the point (12,6).

Question

i do not understand this.

Answer 1

strate line thru point=(12,6)

start line:...4x-3y=12, or y=(4/3)x +sumthun

its slope=4/3

but yer spozed tu make line at 90 deg tu this, so its slope=-1/slope1

slope2=-3/4

thus, y=-(3/4)x+sumthun

projekt line bak from x=12 tu x=0, so deltax=-12

deltay=slope2*deltax=(-3/4)*(-12)=+36/4=9

y=6+9=15

equashun for strate line: y=(-3/4)x+15
