Una recta que pasa por los puntos A (2,1) y B (6,3) y otra recta pasa por A y por el punto (0,y) ¿Cuánto vale y, si ambas rectas son perpendiculares?

The translation of the question given is

A line that passes through the points A (2,1) and B (6,3) and another line passes through A and through the point (0, y). What is y worth, if both lines are perpendicular?

y = 5

Step-by-step explanation:

Line 1 that passes through A (2,1) and B (6,3)  

Slope (m1) = 3-1/6-2 = 2/4 = 1/2

y - 1 = ( x -2)

2y - 2 = x- 2

y =

Line 2 passes through A (2,1) and (0,y)

slope (m2) =

Line 1 and Line 2  are perpendicular

m1*m2 = -1

 * = -1

y-1 = 4

y = 5

slope = -2

Equation of Line 2

Y-1 = -2(x-2)

y -1 = -2x +4

2x +y = 5

x + 4/7

use cymath

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
