How do i solve this?

shusha [124]

Answer:

Step-by-step explanation:

You can use Pythagoras Theorem,

$8^{2} + y^{2} = (8\sqrt{6} )^{2} \\ y^{2} = (8\sqrt{6} )^{2} - 8^{2} \\y^{2} = 384 - 64\\y^{2} = 320\\y = \sqrt{320}$

∴ $y = 8\sqrt{5}$

What's the equation of the line perpendicular to y=-3/2x+4 through the point ( 2,-3)

Korvikt [17]

Because it's perpendicular, you know that they must have the same slope, -3/2. So, just factor that and the point into the slope-point form to get

y = -3/2x
